1. Convert the dimensions of the sheet to inches:
   • Lengte: 4 voeten = 48 inches
   • Breedte: 8 voeten = 96 inches
2. Convert the thickness to decimal form:
   • 3/16 inch = 0.1875 inches
3. Calculate the area of the sheet in square inches:
   • Oppervlakte = Lengte x Breedte = 48 inches x 96 inch = 4,608 square inches
4. Calculate the volume of the sheet in cubic inches:
   • Volume = Oppervlakte x Dikte = 4,608 square inches x 0.1875 inch = 864 kubieke centimeter
5. Convert the volume from cubic inches to cubic feet:
   • Volume (kubieke voet) = Volume (kubieke centimeter) / 1728 = 864 kubieke centimeter / 1728 = 0.5 kubieke voet
6. Determine the density of aluminum. The density of aluminum is typically around 0.098 pond per kubieke inch.
7. Multiply the volume in cubic feet by the density to calculate the weight in pounds:
   • Gewicht (pond) = Volume (kubieke voet) x Density = 0.5 kubieke voet x 0.098 lbs/in³ ≈ 0.049 pond

Daarom, een 4×8 3/16 aluminium plaat would weigh approximately 0.049 pond.
