Question

The density of copper is 9.86 g/cm3.
Work out the mass of the solid copper cuboid in kg. ​

Answer 1

Answer:

$\purple { \bold{ Mass = 1.479 \: kg}}$

Step-by-step explanation:

$V_{copper\:cuboid} \\ = 10 \times 3 \times 5 \\ = 150 \: {cm}^{3} \\ D_{copper\:cuboid} = 9.86 \: g/cm^3 \\ Mass = Volume \times Density \\ = 150 \times 9.86 \\ = 1,479 \: g\\ \purple { \bold{ Mass = 1.479 \: kg}}$
