Find the volume of a pyramid with a square base, where the perimeter of the base is 18, point, 3, in18.3 in and the height of the pyramid is 15, point, 7, in15.7 in. Round your answer to the nearest tenth of a cubic inch.

To find the volume of a pyramid, you can use the formula: V = 1/3 * base area * height.

Step 1: Find the length of one side of the base. The base is a square and the perimeter of a square is given by 4 * side length. So, the side length is the perimeter divided by 4. 18.3 in / 4 = 4.575 in

Step 2: Find the area of the base. The area of a square is side length squared. (4.575 in)^2 = 20.930625 in^2

Step 3: Find the volume of the pyramid. Substitute the base area and the height into the volume formula. V = 1/3 * 20.930625 in^2 * 15.7 in = 109.676171875 in^3

Step 4: Round to the nearest tenth. The volume of the pyramid is approximately 109.7 in^3.

To find the volume of a pyramid, you can use the formula: V = 1/3 * base area * height.

Step 1: Find the length of one side of the base. The base is a square and the perimeter of a square is given by 4 * side length. So, the side length is the perimeter divided by 4. 18.3 in / 4 = 4.575 in

Step 2: Find the area of the base. The area of a square is side length squared. (4.575 in)^2 = 20.930625 in^2

Step 3: Substitute the base area and the height into the volume formula and solve. V = 1/3 * 20.930625 in^2 * 15.7 in = 109.572890625 in^3

Step 4: Round to the nearest tenth. The volume of the pyramid is approximately 109.6 in^3.
