The volume of a rectangular prism is 336 cubic centimeters. The height of the prism is 21 centimeters.
How to find the volume and base area of a right rectangular pyramid?
Suppose the base of the pyramid has length = l units, and width = w units.
Suppose that the height of the pyramid is of h units,
then:
[tex]v = \dfrac{l \times w \times h}{3} \: \rm unit^3[/tex] is the volume of that pyramid.
The base is a rectangle with length = L units, and width = W units, so its area is:
[tex]b = l \times w\: \rm unit^2[/tex]
The volume of a rectangular prism is 336 cubic centimeters.
[tex]v = \dfrac{l \times w \times h}{3} \: \rm unit^3[/tex]
3 x 336 = lwh
lwh = 1008
The area of the base of the prism is 48 square centimeters.
48 x h = 1008
h = 21
