Question

A cube measures 4.7 cm on each edge and has a mass of 63.6 g. Calculate the density of the material that composes the cube.

Answer 1

Answer:

d = 0.612 g / cm³

Explanation:

Density of a substance is given by the mass of the substance divided by the volume of the substance .

$d = \frac{m}{V}$

V = volume

m = mass ,

d = density ,

From the question ,

The mass of the cube = 63.6 g

The volume of the cube -

The edge of the cube = 4.7 cm ,

Since ,

$volume= egde^{3}$

$Volume = 4.7 ^{3}$

Volume = 103.823 cm³

Hence , by using the above formula ,and putting the corresponding values , the density is calculated as -

$d = \frac{m}{V}$

d = 63.6 g / 103.823 cm³

d = 0.612 g / cm³
