Question

A solid rectangular piece of iron measures 5m×6cm×2cm. Find its weight if 1 cu. cm of iron weighs 7.6 grams.

Answer 1

5m =500cm
volume=l*b*h=500*6*2=6000cu.cm
weight of iron in 1cu.cm=7.6 g
then total weight= 7.6*6000=45600g

Answer 2

Its weight is 456 grams

Step-by-step explanation:

Length of iron piece = 5 m

Breadth of iron piece = 6 m

Height of iron piece = 2 cm

Volume of iron piece =$Length \times Breadth \times Height = 5 \times 6 \times 2=60 cm^3$

Weight of 1 cubic cm = 7.6 grams

Weight of 60 cubic cm = $7.6 \times 60 = 456 grams$

Hence its weight is 456 grams
