Convert the units from the American metric system to the British metric system and the standard metric system (SI).
Here are some geometrical bodies, whose volume can be calculated. These are pyramid, truncated pyramid, cylinder, hollow cylinder (pipe), cone, truncated cone, sphere, the segment of a sphere and a barrel. You will have to be consequent with the units. So, if you want the volume in cubic meters, you will have to fill in all the data in meters. If you don't, the calculations will be wrong.
