Answer
$954$ million acres converts to $1,490,625 miles^{2}$
Work Step by Step
To convert from acres to square feet, we multiply the area by 43560 because we are told that $1 acre= 43560 ft^{2}$. $954,000,000 acres×\frac{43560 ft^{2} }{1 acre}=4.156\times10^{13} ft^{2}$. Now we must convert the value to ft by taking the square root so $ft = \sqrt {4.156\times10^{13} }ft^{2} = 6446412.95606 ft$. Then to convert to miles, we divide by 5280 because 1 mile = 5280 ft so $ 6446412.95606 ft \times\frac{1 mi}{5280 ft} = 1220.91154471 mi$. Lastly to get square miles, we must simply raise our answer in miles to the power 2; $1220.91154471 ^{2} = 1,490,625 miles^{2}$
