What is the total number of pipes if a project blueprint requires 5 pipes, each 10 feet long, with a scale of 1/4" = 1 foot?

To determine the total number of pipes based on the project blueprint, start with the requirement of 5 pipes, each measuring 10 feet in length. The scale of the blueprint is 1/4" = 1 foot, which is crucial for translating actual dimensions into scaled dimensions for the blueprint.

Calculating the total length of all pipes is straightforward. Since each pipe is 10 feet long and there are 5 pipes, you simply multiply the length of one pipe by the number of pipes:

5 pipes × 10 feet per pipe = 50 feet.

Therefore, the total length of the pipes required for the project is 50 feet, confirming that this choice accurately reflects the total length needed as indicated in the question. The scale is relevant for understanding real lengths in the context of the blueprint but does not affect the total length calculation directly, as you are asked for the total length in feet. Hence, the answer is indeed 50 feet.
