Thats an inference
1 mL of water equals 1cm^3 of volume, so 1.72 ml= 1.72 cm
To find the volume, use the formula: volume = mass / density. Substituting the values, volume = 3g / 2.7 g/ml = 1.11 ml. The volume of the marble is 1.11 ml.
The density of the marble would be determined by dividing the marble's mass (12.5 g) by its volume (5ml), which would give you 2.5g/ml.
1.1111111111111
Density is calculated by dividing the mass of the object by the volume it displaces. In this case, the density of the marble would be 2.5 g/mL (12.5 g / 5.0 mL).
well it all starts with four marbles..... for mL you would do the following: for example lets use a chalkboard eraser. you would find its volume (for say 135cm3). then you would add how much the marble weighs which may be 2.26796 mL. but lets round that to 2 mL. now you times that by four which is? 8 mL!! now you add 8 mL to 135 mL which equals................................................................................................................................................................................................... 143 mL!! there you go but just to let you know if you need the answers to the Metric mania worksheet go to this website: www.sciencespot.net
For finding volume you can use water displacement. Get a amount of water (make sure you know what number and how much) and drop your item in the water. The water should have risen. The difference of the Displaced water and the starting water should get you your volume.e.g. 16 mL of water, you drop a marble, the water is now 18 mL. So the volume of the marble is 2 mL.
1.72 ml
divide the mass over the volume and the answer is 2.3 D=M over V D=23 over 10=2.3.
The volume of the object is 5.8 mL. This can be calculated by subtracting the initial volume (17.8 mL) from the final volume (23.6 mL).
36 ml IS a volume
2.7 ml
