Question

A rectangle pyramid fits exactly on top of a rectangular prism. the prism has a length of 12in a width of 4in and a height of 5in the pyramid has a height of 10in find the volume of the composite space figure
A. 480in^3
B. 300in^3
C. 2400in^3
D. 400in^3

Answer 1

To find the complete volume you will find the volume of the rectangle or prism and the pyramid separately. Add these together for the total.

Prism:
V = lwh
12 x 4 x 5
V = 240 in.³

Pyramid:
V = 1/3Bh, B is the area of base
V = 1/3 x (12 x 4) x 10
V = 160 in.³

240 in.³ +160 in.³ = 400 in.³ (D)
