As we know 1 miles = 5280 feet.
Firstly we will convert everything into feet.

So Length = 28 miles = 28 * 5280 feet = 147,840 feet

Width = 20 miles = 20 * 5280 feet = 105,600 feet.

Depth = 1 inch= 1 * 1/12 feet = 1/12 feet
(because 1 inch = 1/12 feet)

So Volume = Length * Width * Depth
= 147840 * 105600 * 1/12 = 1300,992,000 cubic feet.

So we can say 1300,992,000 cubic feet rain fell.

In this question, you are given the width( 20 miles), the length(28 miles) and the height( 1 inch). You are asked to count the rain water volume which was going with formula length x width x height. But the unit asked is ft, so you need to convert them all. The calculation would be:

Water volume= length x width x height
Water volume= 20 miles x 5280ft/miles x 28 miles x 5280ft/miles x 1inch x 1ft/12inch
Water volume = 1300992000 cubic ft.
