Question

A cube measures 4.6 cmcm on each edge and has a mass of 63.0 gg. Calculate the density of the material that composes the cube. (The volume of a cube is equal to the edge length cubed.)

Answer 1

Answer:

$0.65gcm^{-3}\text{. Option B is correct}$

Explanations:

The formula for calculating the density of a substance is expressed as:

$\text{Density}=\frac{Mass}{\text{Volume}}$

Given the following parameter:

$\text{Mass of the cube=63.0g}$

Get the volume of the cube:

$\begin{gathered} V=L^3 \\ V=4.6^3 \\ V=97.336\operatorname{cm}^3 \end{gathered}$

Get the required density. Recall that;

$\begin{gathered} \text{Density of cube=}\frac{Mass\text{ of cube}}{Volume\text{ of cube}} \\ \text{Density of cube=}\frac{63.0g}{97.336\operatorname{cm}^3} \\ \text{Density of cube}\approx0.65\text{gcm}^{-3} \end{gathered}$

Therefore the density of the material that composes the cube is 0.65g/cm^3
