Question

The mass of an iron cube having an edge length 1.5 cm is 50g. Find its density.

Answer 1

Density=Mass/Volume

For the iron cube,

Mass=50g
Volume= 1.5³ = 3.375 cm³

So,
Density= Mass/Volume
            =50/3.375
            =14.81481
∴Density≈14.81 g/cm³

Thus, density of the iron cube is  14.81 g/cm³

Answer 2

volume of the cube = 1.5³ = 3.375 cm³
density = mass / volume
density = 50 / 3.375
density of the iron cube = 14.8 gm / cm³
