Subtracting the shortest length from the longest gives:
162 cm
We are given the length of the pipes as follows:
0.81 m 1.08 m 0.8 m 180 cm 18 cm
We have to subtract the shortest length from the longest.
firstly we convert each of the length of pipes into cm
We know that 1 m=100 cm
0.81 m=81 cm
1.08 m=108 cm
0.8 m=80 cm
Longest length=180 cm
smallest length=18 cm
so, 180-18=162
Hence, subtracting the shortest length from the longest gives:
162 cm
