If a straight run of pipe travels through 5 rooms, each measuring 80 feet long, what is the total length of pipe required?

To determine the total length of pipe required for a straight run that travels through 5 rooms, each measuring 80 feet long, you need to calculate the overall length by multiplying the length of one room by the number of rooms.

Each room is 80 feet long, and since there are 5 rooms, you multiply 80 feet by 5:

80 feet/room × 5 rooms = 400 feet.

Therefore, the total length of the pipe required is 400 feet. This calculation reflects the straightforward method for finding the length of pipe when the rooms are aligned in a single straight run.
