Question

The length breadth and height of a room are 6m30cm 5m85cm and 3m60cm respectively what will be the greatest length of a tape which can measure the dimension of a room exact number of times?

Answer 1

Answer:

45 cm

Step-by-step explanation:

First of all we will take the HCF of all but, before that we will convert them in a similar unit :

6m 30cm =6 X 100 + 30

=630cm

5m 85cm =5 X 100 + 85

=585cm

3m 60cm =3 X 100 + 60

=360cm

Now, lets take the HCF :

HCF of 630cm, 585cm, 360cm

= 45 cm
