Answer:
The answer is 6
Explanation:
The volume of a pyramid is: 1/3 * Base * Height.
Base:
The base is this pyramid is a square. To calculate its area it's side * side.
8 * 8 = 64.
64 is the base area. We take it and multiply it by the height and divide by 3 to get the Volume. In this case we don't have the height, but we do have the volume. So we can put a simple equation:
128 (volume) = 64(base area) * Height * 1/3.
Solve for Height:
Height = (128 * 3) / 64
Put this in the calculator and you will get 6.
