Question 930236
a. If one inch of rain fell over one acre, how many cubic inches of water would that be? How many cubic feet?
:
Since we are dealing in feet, use 1/12 ft for 1 inch
We know that 1 acre has an area of 43,560 sq ft
V = 43560 * 1/12 = 3630 cubic ft

b. If one cubic foot of water weighs approximately 62 pounds, what is the weight, in tons, of one inch of rain over one acre of ground?

Find the weight in pounds, 3630 * 62 = 225,060 pounds
