Find the Mass of one cubic meter of a brick if one brick with measurements of 2 decimeters, 15 centimeters and 0.1 millimeters has a mass of 2.7 kg.
1. Determine the mass of one brick, while translating all its dimensions into meters:
2 dm x 15 cm x 0.1 mm = 0.2 x 0.15 x 0.0001 = 0.0000015 m³
2. Determine the mass of one cubic meter of a given brick. We take the unknown mass as a and make up the proportion:
0.0000015 m³ – 2.7 kg, 1 m³ – a kg;
0.0000015: 1 = 2.7: a;
a = (1 x 2.7): 0.0000015;
a = 18,000,000 kg.
Answer: with the given brick parameters, the mass of one cubic meter of brick will be 18,000,000 kilograms.
