What is the length in centimetres of a glass rod 7.82inches long ?
  • 1 answers

Yogita Ingle 4 years, 4 months ago

we know that 1 inch= 2.54 cm

therefore to convert 7.82 into cm we need to multiply it with 2.84 ....

i.e.,  7.82*2.54

= 19.8628

=19.9 cm (since the question has only 3 significant figures)
