Question

Layla is making a square pyramid teepee outside a museum. She needs to know how much space she needs for the base of the teepee. Layla wants the teepee to be 9 feet tall. Determine the dimensions of the base of the teepee if the volume is 432 cubic feet.

Answer 1

12 feet

Explanation:

Volume of a square pyramid

= a²h/3

h = 9 feet

Volume = 432 cubic feet

Base edge(a) =

a = √3V/h

a = √3 × 432/9

a= √3 ×432/9

a = √3 × 48

a = √144

a = 12 feet

The dimensions of the base of the teepee if the volume is 432 cubic feet is 12 feet
