Question

The length, breadth and height of a room is 6m 80 cm, 5m 10 cm and 3 m 40 cm, respectively. Find the longest tape which can measure the dimensions of the room exactly

Answer 1

Answer:

Step-by-step explanation:

The HCF of this will be the length of the longest tape to be used:  

length= 680 cm  = 4 * 170

breadth = 510 cm  = 3* 170

height = 340 cm = 2*170

As we can see the HCF is 170 cm.

Thus the longest tape that can measure the dimensions exactly = 170cm.
