Find the mass of 1 m3 of a brick if one brick with dimensions of 2 dm, 15 cm and 0.1 m has a mass of 2.7 kg.

To find out the mass of 1 m³ of a brick, you need to know its density, which is p = m / V.

The volume of one brick is equal to the product of the lengths of its sides, since the brick is a rectangular parallelepiped, therefore:

V = 0.2 m * 0.15 m * 0.1 m = 0.003 m³, therefore p = 2.7 kg / 0.003 m³ = 900 kg / m³.

Consequently, the mass of 1 m³ of brick will be m = p * V = 900 kg / m³ * 1 m³ = 900 kg.

Answer: m = 900 kg.
