Question

4. Find the length of longest pole that can be placed in a room 12 m long, 8 m broad and 9 m high.​

Answer 1

Answer:

here

l= 12

b=8

h=9

longest pole=√l²+b²+h²

= √12²+8²+9²

=√144+64+81

=√289

= 17m

Answer 2

Answer:

As per the given dimensions it is of cuboid shape

Longest length in a cuboid is its diagonal

So, length of the longest pole = length of diagonal = sq.root( l^2 + b^2 + h^2) = sq.root(12^2 + 8^2 + 9^2) = 17m
