What is finding the volume of a regular solid?Show answer
For a regular shape, calculate the volume from its measurements. For a box (cuboid), volume length width height. Measure each side with a rule, then multiply.
What is finding the volume of an irregular solid?Show answer
For an irregular object such as a stone, use the displacement method:
What is finding the density of a liquid?Show answer
To find the density of a liquid, measure the mass of an empty measuring cylinder, add a known volume of the liquid, and measure the mass again. The mass of the liquid is the difference, and you read its volume from the cylinder. Then divide.
