To find the volume of a pyramid, you can use the formula V = (1/3) * base area * height.
In this case, the base of the pyramid is a triangle with a base of 9 mi and a height of 7 mi, so the base area is (1/2) * base * height = (1/2) * 9 mi * 7 mi = 31.5 mi^2.
The height of the pyramid is given as 6 mi.
Now you can plug these values into the formula to find the volume:
V = (1/3) * base area * height
= (1/3) * 31.5 mi^2 * 6 mi
= 63 mi^3
So, the volume of the pyramid is 63 mi^3.
