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? Hint: convert units to feet first.

Step-by-step explanation:

volume=7.3×1760×3×30×1760×3×1/12=73×176×90×440=508780800 ft³

508,780,800 ft³ of rain

Step-by-step explanation:

In order to do the computation, we need to express all the given lengths in feet.

recall that 1 mile = 5280 feet

hence,

width = 7.3 miles = 7.3 x 5280 = 38,544 feet

length = 30 miles = 30 x 5280 = 158,400 feet

also recall that 1 inch = 1/12 feet

hence,

depth of rainfall = 1 inch = 1/12 feet

Volume of rain = width of beach x length of beach x depth of rainfall

= 38,544 x 158,400 x (1/12)

= 508,780,800 ft³ of rain

15 units use socratic
