1. Convert the dimensions of the sheet to inches:
   • Uzunluk: 4 ayak = 48 inç
   • Genişlik: 8 ayak = 96 inç
2. Convert the thickness to decimal form:
   • 3/16 inch = 0.1875 inç
3. Calculate the area of the sheet in square inches:
   • Alan = Uzunluk x Genişlik = 48 inches x 96 inches = 4,608 square inches
4. Calculate the volume of the sheet in cubic inches:
   • Hacim = Alan x Kalınlık = 4,608 square inches x 0.1875 inches = 864 Kübik inç
5. Convert the volume from cubic inches to cubic feet:
   • Hacim (fit küp) = Volume (Kübik inç) / 1728 = 864 Kübik inç / 1728 = 0.5 fit küp
6. Determine the density of aluminum. Alüminyumun yoğunluğu tipik olarak yaklaşık 0.098 pound bölü inç küp.
7. Multiply the volume in cubic feet by the density to calculate the weight in pounds:
   • Ağırlık (pound) = Volume (fit küp) x Density = 0.5 fit küp x 0.098 lbs/in³ ≈ 0.049 pound

Öyleyse, 4×8 3/16 Alüminyum levha would weigh approximately 0.049 pound.
