Question

A solid rectangular piece of iron measures 1.05m × 70cm × 1.5cm. Find the weight of this piece in kilograms if 1cm³of iron weighs 8 grams.

Answer 1

We know that 1m=100cm

Dimension of the tank is 1.05m and 70cm and 1.5cm.

Also we know that volume of cuboid = length × breadth × height

V = 105 × 70 × 1.5

V = 11025cm³

And we know that 1cm³= 8 grams

Weight of iron piece = 11025 × 8 = 88200g

But 1kg=1000g

Weight of iron piece = 88.2kg
