Question

find the length of the longest pole that can be put in a room dimension 10 m by 10 m by 5 M

Answer 1

The length of the longest pole that can be put in room is the length of its diagonal.
Then,
Diagonal=root l^2+b^2+h^2
=root 10^2+10^2+5^2
=root 100+100+25
=root 225
Hence, Diagonal=15 m
The lenghth of the pole be 15 m.
