The following amounts of nonmetallic sheathed cable are used on an apartment house job: 625 ft, 785 ft, 75 ft, 140 ft, 310 ft, 325 ft, 120 ft. What is the total feet of nonmetallic sheathed cable used on the job?

• A. 2000
• B. 2380
• C. 2500
• D. 2600

Answer: (B)

Adding all the given run lengths gives the total amount of cable used. Each number is a length of NM cable installed in different parts of the job, so you sum them to get the overall quantity.

625 + 785 + 75 + 140 + 310 + 325 + 120 = 2380 feet.

The total is 2,380 feet of nonmetallic sheathed cable, which matches the provided answer.
