Question

the length of largest pillar which can be fit in the room of length 12m, breadth 8m and hieght 6m

Answer 1

Hey mate !!

Here's your answer !!

The longest rod that can be placed in this room is its diagonal. Hence we must find the diagonal of this cuboidal room.

Given: Length = 12 m , Breadth = 8 m , Height = 6 m 

Diagonal of a cuboid = √ ( l² + b² + h² )

Diagonal = √ ( 12² + 8² + 6² )

= √ ( 144 + 64 + 36 )

= √ 244

Hence the length of longest rod that can be placed is √ 244 m.

Hope it helps !!

Cheers !!
