Question

A room is 12 cm wide and 18m long. Find the length of the longest rod that can measure the dimensions of the hall exactly.
answer this as fast as possible

Answer 1

Answer:

17 m

Step-by-step explanation:

Given

length l = 12 m  

breadth b = 9 m  

height h = 8 m  

Longest rod that can be placed in a room is nothing but its diagonal.  

Length of diagonal of a cuboid = √(l2 + b2 + h2)  

Length of longest rod = √(122 + 92 + 82) m  

= √(144 + 81 + 64) m  

= √289 m  

= 17 m  

hence the length of the longest rod is 17 m

Answer 2

Step-by-step explanation:

HERE THE QUESTION IS MISSING

Step-by-step explanation:

Given

length l = 12 m

breadth b = 9 m

height h = 8 m

Longest rod that can be placed in a room is nothing but its diagonal.

Length of diagonal of a cuboid = √(l2 + b2 + h2)

Length of longest rod = √(122 + 92 + 82) m

= √(144 + 81 + 64) m

= √289 m

= 17 m

hence the length of the longest rod is 17 m
