Question

The
length, breadth and height of a box
are 75 cm, 85 cm and 95 cm
respectively. What will be the
greatest length of tape which can
measure the three dimensions of the
box exactly? ​

Answer 1

Answer:

Length = 825 cm =3×5×5×11

Breadth = 675 cm =3×3×3×5×5

Height = 450 cm =2×3×3×5×5

Longest tape = HCF of 825, 675, and 450 =3×5×5=75cm

Therefore, the longest tape is 75 cm.
