To find the volume of a pyramid with a square base, you can use the formula: V = (1/3) * base area * height.
1. Calculate the area of the square base:
Given the side length of the base is 6.6 in, the area of a square is side length squared. So, area = 6.6 in * 6.6 in = 43.56 square inches.
2. Plug the values into the volume formula:
V = (1/3) * 43.56 square inches * 7.7 in = (1/3) * 43.56 * 7.7 in = 112.144 cubic inches.
3. Round the answer to the nearest tenth:
The volume of the pyramid is approximately 112.1 cubic inches.
