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

Answer :

From the figure, FD is the longest pole that can be put in the cuboid.

Given: l = 10 m

b = 10 m

h = 5 m

First in right-angled triangle CBF, applying the Pythagoras theorem we get,

CF = 10√2 m

Now, we have to calculate FD, so applying the Pythagoras theorem in right-angled triangle DCF, we get,

DF

^{2}= 225

DF = √225

DF = 15 m
