A machine shop worker records the mass of an aluminum cube as 176 g. If one side of the cube measures 4 cm, what is the density of the aluminum?

[tex]\text{Density} = \frac{\text{mass}}{\text{volume}}[/tex]

Answer :

To find the density of the aluminum cube, we need to use the formula for density:

[tex]\[ \text{Density} = \frac{\text{mass}}{\text{volume}} \][/tex]

We'll follow these steps:

1. Calculate the Volume of the Cube:

Since the object is a cube, its volume can be calculated using the formula for the volume of a cube, which is:

[tex]\[ \text{Volume} = \text{side length}^3 \][/tex]

We're given that each side of the cube measures 4 cm. So we calculate:

[tex]\[ \text{Volume} = 4 \, \text{cm} \times 4 \, \text{cm} \times 4 \, \text{cm} = 64 \, \text{cm}^3 \][/tex]

2. Determine the Density:

We know the mass of the aluminum cube is 176 grams. Now we can use the volume we calculated to find the density:

[tex]\[ \text{Density} = \frac{\text{mass}}{\text{volume}} = \frac{176 \, \text{g}}{64 \, \text{cm}^3} \][/tex]

[tex]\[ \text{Density} = 2.75 \, \text{g/cm}^3 \][/tex]

So, the density of the aluminum cube is [tex]\( 2.75 \, \text{g/cm}^3 \)[/tex].
