Question

The U.S. has about 190 million acres of national forest. One square mile is the same as 640 acres. How many states the size of Wyoming will cover the same area as all the national forests in the U.S.? Wyoming is shaped much like a rectangle. It is about 352 miles long and 278 miles wide:

Answer 1

Around 3

Explanation:

It is given that 1 sq. mile is equal to 640 acres.

Let's convert 190 million acres to sq. miles.

`190,000,000*(1Sq.Mi.)/(640Acres)=296,875Sq.Mi.`

Taking Wyoming as a rectangle, we can find the area of Wyoming by multiplying length (352 miles) with width (278 miles).

Area of Wyoming is
`352*278=97,856`

To find the number of Whyoming's in total area of national forests, we divide the area of national forests (in sq. mi.) by the area of Wyoming ( in sq. mi.):

`(296,875)/(97,856)=3.03`

So, around 3 Wyoming states' area will cover the area of national forests in US.
