Question

Given: ABCD pyramid All edges congruent AB = 4.5 Find: V

Answer 1

The volume of the pyramid is 30.375 cubic units.

(Assuming that it's a square pyramid).

Explanation:

The volume of a pyramid is

`V=(1)/(3) e^(3)`

Where
`e` represent edges.

If all edges are congruent that means
`e=4.5`, replacing this value, we have

`V=(1)/(3)(4.5)^(3) \\ V=(1)/(3)(91.125) = 30.375`

Therefore, the volume of the pyramid is 30.375 cubic units.
