Question

a plumber cut 2 length of pipe measuring 2.8 and 1.4 meters from a 6 meters length assuming there was no waste when the cuts were made what is the length in meters of the remaining piece A. 1.8B. 3.2C. 4.2D. 7.4

Answer 1

We have the following:

To calculate the value of the remainder, we must subtract the total value (6 meters), the other parts, that is, the part of 2.8 meters and the part of 1.4 meters.

`6-2.8-1.4=1.8`

Therefore, the answer is A. 1.8
