Determine the mass of a brick measuring 250x120x60 cm. The density is 1.8 g / cm3.

Initial data: L (brick length) = 250 cm; S (brick width) = 120 mm; h (brick thickness) = 60 cm.
Reference data: according to the condition ρ (brick density) = 1.8 g / cm ^ 3 = 1800 kg / m ^ 3.
SI system: L = 250 cm = 2.5 m; S = 120cm = 1.2m; h = 60 cm = 0.6 m.
1) Determine the volume of the brick: V = L * S * h = 2.5 * 1.2 * 0.6 = 1.8 m ^ 3.
2) We calculate the mass of the brick: m = V * ρ = 1.8 * 1800 = 3 240 kg.
Answer: The brick mass is 3 240 kg.
