Consider a right prism of any type of base.

If the area of the base is B, consider a prism with that base area that is 1 unit high.

To find the volume of the right prism, multiply this base by the height.

This verifies the following conjecture for the volume of a prism:

V = B x h

V is the volume
B is the area of the base
h is the height

Consider two prisms that have the same base and height but look very different:

Image of five cartons of tuna fish stacked but leaning to the side; Image of five cartons of tuna fish stacked straight up

oblique prism
right prism

There are two stacks of cartons of tuna in a warehouse, one stack is straight up and down, but the other stack is leaning to one side.
