Answer:
6 feet
Step-by-step explanation:
A square pyramid can be called a pentahedron because it has five faces: four triangular faces and one square face.
Given base length a = 2 feet
Given volume = 8 cubic feet
But volume of a square pyramid with base a units and height h units is
Volume v = 1/3a2h
On replacing the given a and V values
8 = 1/3 × 22 × h
⇒ 8 = 4 h /3
On dividing both the sides by 4
⇒ h = 6 feet
