He construction company is digging a drainage trench. It makes the shape of an upside down rectangular pyramid. The top opening will be 30 feet wide by 250 feet long in the deepest part in the middle will be 15 feet. What is the capacity for this trench
To find the capacity of the trench, we need to calculate the volume of the upside down rectangular pyramid.
The formula for the volume of a rectangular pyramid is given by: V = (1/3) * length * width * height.
The length of the trench is given as 250 feet, the width is given as 30 feet, and the height is given as 15 feet.
Substituting these values into the formula, we get: V = (1/3) * 250 feet * 30 feet * 15 feet
V = (1/3) * 112,500 cubic feet
V = 37,500 cubic feet
Therefore, the capacity of the trench is 37,500 cubic feet.
