Question

What is the mass of a rectangular iron block, 10 cm x 20 cm x 30 cm?

Answer 1

The mass of a rectangular iron block, 10 cm x 20 cm x 30 cm will be 46.8 kg

- Volume of given iron block = 10 cm × 20 cm × 30 cm

Volume of given iron block = 6000 cm³

- We know that the density of iron = 7.8 gm/cm³

- As we know,

Density = Mass/ Volume

So,

Mass = Density × Volume

- putting the values of density and volume in this equation, we get

Mass = 7.8 gm/cm³ × 6000 cm³

Mass = 46800 gm

= 46.8 kg
