How do find volume?

If it is a regular solid, meaning all of the sides of the 3 dimensional figure are flat, then you measure and multiply length, width, and height.

However, most objects are not regular solids (such as grapes or hands, etc.), so you can follow these steps:

1) pour water into some sort of container that measures the volume of liquids

2) put the object in the water (the entire object must be under water)

3) subtract the difference between the volume of the water before and after the object was put under water.

If you do not want to get your precious items wet, you can use the following steps:

1) find the mass of the object

2) if you happen to know the density object, which is unlikely considering the fact that you do not know the volume of the object, then find it

3) divide mass/density
