The actual block is 1800 feet long and 1260 feet wide. We know that 1 foot is equivalent to 12 inches.
Luke is now using the Feet scale measurement.
Solving for the area in square inches is shown below: Area = L * W Area = (1800 feet *12 inches/1 foot) * (1260 feet *12 inches/1 foot) Area = 326.592 x10^6 inches²
