1. Convert the dimensions of the sheet to inches:
   • Roaraa: 4 = 48 Te mau nota
   • Te huru â te huru: 8 = 96 Te mau nota
2. Convert the thickness to decimal form:
   • 3/16 inch = 0.1875 Te mau nota
3. Calculate the area of the sheet in square inches:
   • Area = Length x Width = 48 inches x 96 inches = 4,608 square inches
4. Calculate the volume of the sheet in cubic inches:
   • Volume = Area x Thickness = 4,608 square inches x 0.1875 inches = 864 cubic inches
5. Convert the volume from cubic inches to cubic feet:
   • Buka (cubic feet) = Volume (cubic inches) / 1728 = 864 cubic inches / 1728 = 0.5 cubic feet
6. Determine the density of aluminum. The density of aluminum is typically around 0.098 pounds per cubic inch.
7. Multiply the volume in cubic feet by the density to calculate the weight in pounds:
   • Te faito teiaha (lbs) = Volume (cubic feet) x Density = 0.5 cubic feet x 0.098 lbs/in³ ≈ 0.049 lbs

No reira, a 4×8 3/16 api no te mau hoho'a would weigh approximately 0.049 Te mau mana'o tauturu no te.
