Answer:

The football field is 4320 inches long.

Explanation:

Since we're told that 12 in = 1 ft and 3 ft and 1 yd, we can first convert 120 yards to feet and then convert to inches using proportions:

Converting 120 yards to feet:

120 yards / x feet = 1 yard / 3 feet

(120/x = 1/3) * x

(120 = 1/3x) / (1/3)

(120 = 1/3x) * 3

360 = x

Thus, 120 yards is the same as 360 ft.

Converting 360 feet to inches:

360 feet / x inches = 1 foot / 12 inches

(360 / x = 1/12) * x

(360 = 1/12x) / (1/12)

(360 = 1/12x) * 12

4320 = x

Thus, the 120-yard long football field is 4320 inches long.
