Find the volume of a pyramid with a square base, where the side length of the base is 18, point, 2, in18.2 in and the height of the pyramid is 28, point, 8, in28.8 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
First, find the area of the square base:
Area = side length^2
Area = 18.2^2
Area = 331.24 sq in
Now, plug the values into the volume formula:
V = (1/3) * 331.24 * 28.8
V = (1/3) * 9543.552
V = 3181.184 cubic inches
Therefore, the volume of the pyramid is 3181.2 cubic inches.
