The formula for the volume of a regular pyramid is V 13bh where b is the area of the base of the pyramid the polygon at the bottom and h is the height of the pyramid or the vertical distance from the base to the apex point. Calculating the volume of a tube essentially involves the same formula as a cylinder volumepr2h except that in this case the diameter is used rather than the radius and length is used rather than height. Prisms and prism-like figures. If a square has one side of 4 inches the volume would be 4 inches times 4 inches times 4 inches or 64 cubic inches.
