Q3 of 35 Page 74

The length, breadth, and height of a cuboidal room are 5m, 4m and 3m respectively, Let us write the length of the longest rod which can be kept in that room.

Given, length of the room = 5 m

breadth of the room = 4 m


and height of the room = 3 m


Therefore, length of the longest rod = length of the body diagonal


=


=


= √50 = 5√2 m
