Question

1. Length, breadth and height of a box are 75cm, 85cm and 95cm respectively. Find the longest tape which can measure the three dimensions of the room exactly.

Answer 1

Answer:

5cm

Step-by-step explanation:

Length = 75cm = 3 x 5 x 5cm

Breadth = 85cm = 5 x 17cm

Height = 95cm = 5 x 19cm

HCF = 5cm

With a tape of 5cm:

The Length can be measured exactly by 15 times;

The Breadth can be measured exactly by 17 times; and

The Height can be measured exactly by 19 times
