Solution

Height of Sam = 108 cm
168 cm can be estimated as 110 cm.

Height of the room = twice the height of Sam = 2 x 110 cm
= 220 cm

Estimating the length of each iron rod same as the height of the room.
Length of each iron rod = 220 cm

So, the total length of all the 4 iron rods = 4 x length of 1 iron rod
= 4 x 220 cm
= 880 cm
