Let the width = x then we have that length = 2x + 5 and also that:
x + x + 2x + 5 + 2x + 5 = 70
6x + 10 = 70
6x = 60
x = 10
Therefore width = 10ft and length = 25ft
The volume of a pyramid is 1/3 the volume of a prism with the same area and height.
Volume of the pyramid would be 18/3 = 6 in^3
If I am correct it would be 37.5 meters.
