A solid rectangular piece of iron measures 1.05 m x 70 cm x 1.5 cm. Find the weight of this piece in kilograms if 1 cm3 of iron weighs 8 grams.
We know that,
1m = 100cm
Therefore,
Dimensions of the iron piece will be: 105 cm × 70 cm × 1.5 cm
We know that,
Volume of cuboid = Length × Breadth × Height
Total volume of the piece of iron = 105 × 70 × 1.5
= 11025 cm3
We also know that,
1 cm3 = 8 gms
Therefore,
Weight of the piece = 11025 × 8
= 88200 g
=
= 88.2 kg
