According to Baidu Encyclopedia, seeking V from sh belongs to the formula for calculating the volume of a cylinder. The volume of a cylinder is equal to the product of the bottom area and the height of the cylinder. Finding v from sh is based on volume V= bottom area Sx and height h, so v=sh.

V=Sh is a mathematical formula for calculating the volume of all right-angle prisms and cylinders, so this formula is also called the unified formula.
