Question

A block of iron has dimensions 1.5m x 0.5m x 0.25m. The density of iron is 7.8 g/cu.cm. Find the mass of the iron block in kg. ​

Answer 1

Answer:

1462.5 Kg

Explanation:

Let mass of iron block be 'x'

Volume = (1.5 x 0.5 x 0.25)m^3 = 0.1875 m^3

1m^3 = 10,00,000 cm^3

Therefore 0.1875 m^3 = 187500 cm^3

The density of iron block is given as 7.8 g/cm^3

Therefore, density = mass/volume

7.8 = x/187500

x = 7.8 x 187500

x = 1462500 gram

x = 1462.5 Kg

Hope this helps
