Is multiplying the length x width x height a good method to find the volume of a rock?
No. I say this because a rock is usually circular and not a perfect figure. :-)
What is the length width and height of a rock that has the mass of 45g and the volume of 15 cm3?
It's impossible to say definitively. One possible answer would be 2cm x 2.5 cm x 3cm, but it could also be a cube with sides equal to the cube root of 15, or an infinite number of other possibilities. (The mass is superfluous information for this question.)
If a right circular cylinder with radius 7 Cm contains 1077 cm cubed of water a rock is measured in the water and the level rises 3 cm what is the volume of the rock?
First obtain the height of the cylinder. Height = 1077/area of the base (i.e H = 1077 divided by pie-radius-squared) Next get how much water does 1cm of height contain. Take 1077/height. Therefore, volume of rock = 1cm height's volume x 3
What is the width of a wooden block?
That depends on how wide it is.What's the weight of a rock? What's the volume of a ship? How tall is a tree? We can't answer without more details.
How could you figure out the volume of an irregular solid such as a rock?
Fill a bowl of water that is bigger than the rock right to the top, add the rock, collect and measure the volume of how much water is spilt. Provide the rock is not porous or very soluble this will provide the volume of the rock.
How do you find out the volume of a rock?
Height times width times length equals the volume of the rock.

How do you get the volume of rock?
To calculate the volume of a rock, you can use the formula for the volume of a sphere (4/3 * pi * r^3) if the rock is spherical, or use the formula for the volume of a rectangular prism (length * width * height) if the rock has a more regular shape. Otherwise, you can measure the volume by water displacement: submerge the rock in water and measure the increase in water level to find its volume.
How many sheets of sheet rock for a room?
It depends on the size of the room. You need to measure the area to be covered and the area of the sheet rock
What information about a mineral or rock is needed to determine its density?
To determine the density of a mineral or rock, you need to know its mass and volume. Mass can be measured using a scale, while volume can be calculated using measurements of length, width, and height or through displacement of water. The formula for density is density = mass / volume.
Does a ruler measure volume?
No, not with any degree of precision, anyway. A ruler is a linear measuring device; that is, it's good for measuring distances that are in straight lines. Volume is the amount of space an item occupies. To measure volume requires making three linear measurements, one for length, one for width(or depth), and one for height. But if your object is irregularly shaped, as a rock surely is, well, a ruler isn't going to do the job. Not very well, at least. You could grossly approximate the volume of the rock by measuring its dimensions roughly. In other words, if the rock is "about" six inches long and about three inches wide and about four inches high, then its volume is about 6 x 3 x 4 = 72 cubic inches (or inches cubed). But that is a very inexact calculation, because the rock is not a perfect parallelepiped. (What the heck is THAT? Double click the word for a definition.) A set of calipers would be better than a ruler, but your approximation would be only a bit better. To really determine the volume of the rock, you could submerge it in water and measure the amount of water it displaces. It might be a cool experiment to take a rock and approximate its volume with a ruler, calipers, and a beaker of water, to see how accurate (or inaccurate) each method is.
Formula to calculating volume of granite rock before blasting on quarry?
The length times width times the depth of the holes of the bench times the amount of emulsion in the holes
How would you find the volume of an irregular shaped object like a rock?
You would measure the length width and heighth. Then you would multiply them all together. <><><> A better means would be to have a container that the rock will fit in, and fill it full of water. Place the rock in the container, which will overflow. Then remove the rock, and measure the volume of water you have to pour into the container to make it full again. The volume of the water will equal the volume that was displaced by the rock.
What apparatus would you use to measure the size of a rock?
A ruler or a measuring tape could be used to measure the dimensions (length, width, height) of a rock, while a scale can determine its weight. For irregularly shaped rocks, a water displacement method can be used to calculate volume, which can then be used to estimate density or mass.
When a rock is placed in a graducated cylinder containing water the height of the water will?
increase, as the rock displaces a volume of water equal to its own volume. This causes the water level to rise in the graduated cylinder.
Describe a method that the student could use to find the volume of this rock?
The student can find the volume of the rock by using the water displacement method. First, fill a container with water and note the water level. Then, submerge the rock in the water and measure the new water level. The difference in water levels gives the volume of the rock.
