If the coil now has 41,710 turns and each turn is 1.75 inches long, how many feet of wire are required, rounding up?

• A. 6,082 ft
• B. 6,083 ft
• C. 6,084 ft
• D. 6,085 ft

Answer: (B)

This question tests how to compute total wire length from the number of turns and the length per turn, with unit conversion and rounding up.

First multiply the number of turns by the length of each turn: 41,710 × 1.75 inches = 72,992.5 inches of wire in total. Convert inches to feet by dividing by 12: 72,992.5 ÷ 12 = 6,082.7083 feet. Since we must round up to ensure enough wire, we round 6,082.7083 up to 6,083 feet. So you need 6,083 feet of wire.
