a beach is 7.3 miles wide and 30 miles long. If one inch of rain falls on this beach, how many cubic feet of rain fell in this area?

196944 ft^2

Step-by-step explanation:

this is because 7.3 times 63360 is 462528

and 30 times 63360 is 1900800

when you add those two numbers, you get, 2363328

Next, You have to divide that by 12 to get how many feet that is. Which is 196944

508,780,800 cubic feet.

Step-by-step explanation:

This is equivalent to the volume of a huge prism.

V = 7.3 miles * 30 miles * 1 inch

Convert to feet (there are 5280 feet in a mile), and 1 inch = 1/12 of a foot:

Number of cubic feet which fell

= 7.3 * 5280 * 30 * 5280 * 1/12

= 508,780,800 cubic feet.
