Question

Find the length of the longest pole that can be put in a room of dimensions 10 m x 10 m x 5 m.

• A. 15 m
• B. 16 m
• C. 10 m
• D. 12 m

Answer 1

The correct option is A 15 m

the longest pole is equal to the diagnol of the room and the formula for the diagonal of the room is $\sqrt{(l^2+b^2+h^2)}$ which gives us:

$\sqrt{100+100+25}=\sqrt{225}=15m$
