Find the height of a square pyramid that has a volume of 12 cubic feet and a base length of 3 feet.
1.5 feet
2 feet
3 feet
4 feet

Answer 1

Volume of a square pyramid is
V= a^2 * h/3
We know that V= 12 and a= 3 so substitute
12 = 3^2 * h/3
12 = 9 * h/3
Divide both sides by 9
12/9 = h/3
1.33 = h/3
Multiply 3 by both sides
3 * 1.33 = h
4 = h
