Answer 2

The density of the aluminum is 2.75 g/cm³ if mass of an aluminum cube is 176 g and one side of the cube measures 4 cm

Given:

• Mass of Aluminum cube = 176 g
• Side of the cube = 4 cm

To Find:

• Density of the Aluminum

Solution:

Volume of the cube = ( side length)³

Step 1:

Find Volume of the aluminum cube

Volume = 4³ = 64 cm³

Density is given as mass divided by volume

$\text{density}=\dfrac{\text{mass}}{\text{volume}}$

Step 2:

Calculate density by substituting mass = 176 g  and Volume = 64 cm³

$\text{density}=\dfrac{176}{64}\\\\\text{density}=\dfrac{44}{16}\\\\\text{density}=\dfrac{11}{4}\\\\\text{density}= 2.75$

The density of the aluminum is 2.75 g/cm³
