siimple thisVolume = (1/3) * base area * height

Given that the base area is 200 square meters and the height is 75 meters, you can plug these values into the formula:

Volume = (1/3) * 200 * 75
Volume = (1/3) * 15000
Volume = 5000 cubic meters

Therefore, the volume of the rectangular pyramid is 5000 cubic meters.
