To measure the weight of a 4×8 aluminum plate with a thickness of 2mm, itu dapat dihitung dengan langkah-langkah berikut:

Hitung luasnya: Pertama, convert the dimensions of the 4×8 aluminum sheet to square meters (atau sentimeter persegi, tergantung pada unit mana yang biasa Anda gunakan). For a 4×8 lembaran aluminium kaki, luasnya dapat dinyatakan dalam kaki persegi (persegi. kaki), yang kemudian dapat dikonversi ke meter persegi (persegi. M) atau sentimeter persegi (persegi. cm).
1 square foot ≈ 0.0929 square meters
1 square foot ≈ 929 square centimeters
Calculate the volume: multiply the area by the thickness of the aluminum plate to get the volume of the aluminum plate. Note that the thickness here should be expressed in meters (M) or centimeters (cm).

Calculating Weight: The density of aluminum is usually expressed in grams per cubic centimeter (gram/cm³). Aluminum has a density of about 2.7 grams per cubic centimeter. By multiplying the volume of the aluminum plate by the density of the aluminum, you can find the weight of the aluminum plate.

Misalnya, assuming that the aluminum sheet measures 4×8 kaki and is 2mm thick:

Luas = 4 kaki x 8 feet = 32 square feet ≈ 2.97 square meters
Volumenya = 2.97 square meters x 0.2 cm (2 mm to cm) = 0.594 cubic meters
Weight = 0.594 cubic meters x 2.7 grams per cubic centimeter ≈ 1,604.2 grams
Jadi, this 2mm thick 4×8 aluminum plate weighs about 1,604.2 grams, or about 1.6 kilograms.
