Final answer:
To find the thickness of the aluminum, you can use the formula: Density = Mass/Volume. By substituting the given values into the formula, we can calculate that the thickness of the aluminum is approximately 0.059 cm or 0.59 mm.
Step-by-step explanation:
To find the thickness of the aluminum, you can use the formula:
Density = Mass/Volume
The mass of the aluminum is given as 20.34g and the density is given as 2.7 g/cm³. We can rearrange the formula to solve for the volume:
Volume = Mass/Density
Now, we can substitute the values into the formula:
Volume = 20.34g / 2.7 g/cm³
Volume ≈ 7.55 cm³
The thickness of the aluminum can be calculated using the formula:
Thickness = Volume / (Length × Width)
Substituting the values:
Thickness = 7.55 cm³ / (45 cm × 23 cm)
Thickness ≈ 0.059 cm or 0.59 mm
