Answer

Square feet in half a square mile.

Reasoning

There are 3 feet in a yard, 1760 yards in a mile, and 8 furlongs in a mile.

A mile is 1760 x 3 = 5280 feet in a mile.

A square mile is 5280 x 5280 = 27878400 square feet.

Therefore half a square mile = **13,939,200** square feet.

A furlong is 1760 ÷ 8 = 220 yards.

Therefore a cubic furlong is 220 x 220 x 220 = **10,648,000** cubic yards.
