How to Find the Volume of a Square Based Pyramid
- 1). Measure the length of one side of the pyramid base. Multiply the length of the side by itself to find the area of the pyramid base. The area of a square is the length of the side squared. For example, if the length of the side is 50 feet, the area is 2,500 square feet -- 50 x 50 = 2,500. Record this value.
- 2). Divide the base area by three. For example, if the base area is 2,500 square feet, divide by 2,500 by 3. In this example, the result would be 833.33 square feet.
- 3). Measure the height of the pyramid from the center of the base to the apex. Record this value. Multiply the height of the pyramid by the result from Step 2. The result is the volume of the pyramid.
For example, if the height is 60 feet, then the volume is 50,000 cubic feet -- 60 x 833.33.
