If the base is a rectangle, use the formula for the area of a rectangle.

Depends whether you want the formula for surface area, volume, perimeter, size of sphere it would fit into etc... Please clarify next time.

The formula will depend on what it is that you are trying to find: the volume or the surface area.

Suppose that the area of the rectangular base is: lw then if the height is: h the surface area is: lw + lh + wh I believe that formula is for the surface area of a rectangular prism...

Surface area = 2LW + 2(L+W)H
