Question

The length, breadth, and height of a room are 8.25 m, 6.75 m and 4.50 m respectively. Find the largest tape that can measure the three dimensions exactly. ​

Answer 1

Answer:

So, the H.C.F of 8.25 m , 6.75 m and 4.5 m is 0.75 m. Hence , answer is 0.75 m ( 75 cm )

Answer 2

Answer:

L = 8.25 m = 825 cm

825 = 3 * 5 * 5 * 11

B = 6.75 m = 675 cm

675 = 3 * 3 * 3 * 5 * 5

H = 4.50 m = 450 cm

450 = 2 * 3 * 3 * 5 * 5

HCF (825, 675, 450) = (3 * 5 * 5) = 75.

So, longest tape of 75 cm length can be used.
