The length, breadth and height of a rectangular iron block are 8 centimetres, 5 centimetres and 2 centimetres. What is its volume?

The weight of 1 cubic centimeter of iron is 7.8 grams. What is the weight of the iron block?

Open in App

Solution

Length of the rectangular iron block = 8 cm

Breadth of the rectangular iron block = 5 cm

Height of the rectangular iron block = 2 cm

Volume of the rectangular iron block = Length × Breadth × Height

= 8 cm × 5 cm × 2 cm

= 80 cm³

Weight of 1 cm³ of iron = 7.8 g

∴ Weight of 80 cm³ of iron = 7.8 × 80 g = 624 g

Thus, the weight of the iron block is 624 g.
