One pound= 454 grams
One pound =16 ounces
16 ounces= 454 grams
1 ounce= 28.4 grams
12 ounce= 12×28.4 grams
= 340.8 grams
Density of Aluminum = 2.70 g mL⁻¹
Volume of Aluminum = [tex]\frac{340.8}{2.7}[/tex]
=126.2 mL
=126.2 cm³
[tex]75 ft^{2} \times 12 \frac{in}{ft} \times 12 \frac{in}{ft} \times 2.54 \frac{cm}{in} 2.54 \frac{cm}{in} = 69,677.28 cm^{2}[/tex]
69,677.28 cm²× Thickness = 126.22 cm³
Thickness:
[tex]\frac{126.22 cm^{3}}{69,677.28 cm^{2}} = 0.00181 cm[/tex]
