79200 feet is the volume of great wall.
Step-by-step explanation:
1 mile = 5280 feet
5280 feet × 15 feet = 79200
The height is the thing that we don't need to use, because you need volume, volume is the place where the wall at, the place is 79200 feet.
And I have question for you, have you ever go to China, did you go to the great wall, where did you come from.
1 acre = 43560 square feet
43560 = 484 * X
X=43560/484 = 90
the width = 90 feet
