Answer:
The number of pipes to be cut from total length of pipe is 10 pipes
Explanation:
Given as :
Total length of pipe = l = 7
foot
i.e ' =
foot
The length of pipe to be cut = l' =
foot
Let The number of pipes to be cut = n pipes
According to question
The number of pipes to be cut =

i.e n =

Or, n =

Or, n =

or, n = 5 × 2
∴ n = 10 pipes
So, The number of pipes to be cut = n = 10 pipes
Hence, The number of pipes to be cut from total length of pipe is 10 pipes Answer
