Question

The length, breadth and height of a room are 825 cm, 675 cm and 450 cm respectively. Find the
longest tape which can measure the three dimensions of the room exactly.

​

Answer 1

Answer:

Longest tape= Total surface area

Answer 2

Answer: 75 cm

Step-by-step explanation:

Given,

Length: 825 cm

Breadth: 675 cm

Height: 450 cm

We need to find the longest tape. Since measuring tape would be smaller than 825, 675 and 450, we find HCF.

Therefore,

825 = 3 x 5 x 5 x 11

675 = 3 x 3 x 3 x 5 x 5

450 = 2 x 3 x 3 x 5 x 5

So HCF = 3 x 5 x 5

Longest measuring tape = 75 cm.

Hope it helps!
