What is the the volume of the rock if the water level rises to the 120 ml mark?
It would be 60 ml
Explain two ways to find volume of a plastic cube?
1. Measure the length of one of the sides and cube it (ie multiply the length by the length by the length) 2. Get a bowl with enough water to cover the cube; mark the level of the water; submerge the cube in the water and mark the new level of the water. The volume of the cube is the volume between the two marks - this can be measured by removing the cube and using a measuring jug to measure the amount of water that is needed to be added to raise the water from the first mark to the second mark.
How do you find the volume of the rock?
By its mass sweety. :) * * * * * It depends on the size of the rock. If you can lift it, find a container that is big enough to hold it. Put that container inside a collecting tray. Fill the container with water (or another liquid) to a level at least as high as the rock. Mark that level. Put the rock in the container gently. Measure the rise in the level of water and, if appropriate, collect the water that overflowed into the collecting tray. Calculate the difference in the two water levels. Add the overflow volume if appropriate. That sum is the volume of water displaced by the rock and so the volume of the rock. If the rock is too massive to lift or be contained in something you will need to estimate its volume. That can be done by profiling its shape and partitioning that into smaller, more regular shapes. Calculate the volumes of all those shapes and sum the answers.
How do you get cubic centimeters?
If it is for volume, then you first need a graduated cylinder. Put water in there, then put an object in there, and then mark and record the difference. If it is a 12 milliliter (mL) difference, then it is 12 cm3, since 1 mL = 1 cm3
How do you find the volume of an irregular glass stopper?
Take a large enough clear rectangular tank and pour in a volume of water that is large enough to take the stopper.Mark on the tank the top of the water.Drop the stopper into the water.Find the increase in volume of the water by finding the increase in height of the watervolume = cross-sectional_area_of_tank x increase_in_height_of_waterExample.Suppose the tank is 10cm (wide) by 15 cm (long) by 30cm (high).Pour water in it and it comes to about 20 cm (exact height does not matter) and this is marked on the tank.The stopper is dropped in and the new top of the water is 1.2 cm above the mark (of the previous stop of the water).volume stopper = cross-sectional_area x increase_in_water_level= (10 cm x 15 cm) x 1.2 cm= 180 cm3
What is the the volume of the rock if the water level rises to the 120 ml mark?
It would be 60 ml
A 15 gram solid object is dropped into agraduated cylinder containin 35 ml of water the water level rises to 45 ml mark what is the density of the solid?
the object volume is equal to the water displaced, or 10ml. Density is 15/10 = 1.5g/ml
A piece of metal was gently lowered into a measuring cylinder containing water.The level of water was at 20 cubic metre mark, what is the volume of metal?
The volume of the metal can be calculated by measuring the volume of water displaced after the metal was placed in the cylinder. If the water level rose to the 25 cubic meter mark after the metal was added, then the volume of the metal is 5 cubic meters.

Explain how you would find the volume of an object such as a paper clip?
The easiest way to find the volume of irregular objects is to use water displacement Fill a beaker or other container with water and place the paper clip in the water. The amount the water level rises is the volume of the paper clip. Of course because a paper clip is so small you would either need to use highly accurate measuring devices or place enough paperclips in the water that there is a noticeable change in water level. you would then divide the change in water level by the number of paperclips you put in to get the average volume of a single paper clip.
How could you find the volume of a person?
Fill a cylindrical pool (a pool with vertical sides) with water and measure the level of water in it. Sumberge the human body and measure the level of water. Volume of body = increase in volume in pool = area of cross section of pool * increase in height of water. The pool need not be cylindrical, but being so makes the calculations simpler.
Why is it important to read the water volume with your eye at the same level as the surface of the water?
Reading the water volume at eye level ensures an accurate measurement by minimizing parallax error, which occurs when the water level appears higher or lower than it actually is due to the viewing angle. This technique helps to ensure precise readings and avoid miscalculations in volume measurements.
How will you find the volume of stone using measuring cylinder?
The volume of the stone is measured by displacement. Water is put into the measuring cylinder to a noted mark. The stone is placed in the cylinder and the water level will rise. The difference between the two levels is the volume in ml of the stone.
How would you calculate the density of an irregular object that does not fit inside a graduate cylinder?
One way to calculate the density of an irregular object is to measure its mass using a scale. Next, you can calculate its volume by displacement method - submerge the object in water in a container and measure the volume of water displaced. Finally, divide the mass by the volume to find the density.
How is the density of a small solid sample whose mass and volume is difficult to measure is determined?
The density of a small solid sample can be determined by using the displacement method. This involves submerging the sample in a known volume of liquid (such as water) and measuring the volume of liquid displaced. The density is then calculated by dividing the mass of the sample by the volume of liquid displaced.
A stone has a mass of 75.0g It is placed in a graduated cylinder with 50mL of water The water rises to the 85mL mark Find the density of the stone?
The volume of the stone is equal to the difference in water levels before and after the stone was added, so the volume of the stone is 85mL - 50mL = 35mL. To find the density, divide the mass of the stone (75.0g) by its volume (35mL). The density of the stone is 75.0g / 35mL ≈ 2.14 g/mL.
A stone is placed on a graduated cylinder which has been filled to the 35-ml mark The level rises to 42 ml What is the volume of the stone?
The Volume of the rock is 7-2=5 ML then the Density of the rock is 25g/5ml=5 g/ml
