To measure the weight of a 4×8 aluminum plate with a thickness of 2mm, se voidaan laskea seuraavilla vaiheilla:

Laske pinta-ala: Ensimmäinen, convert the dimensions of the 4×8 aluminum sheet to square meters (tai neliösenttimetriä, riippuen siitä, mihin yksiköihin olet tottunut). For a 4×8 foot aluminum sheet, pinta-ala voidaan ilmaista neliöjalkoina (sq. ft.), joka voidaan sitten muuntaa neliömetriksi (sq. m) tai neliösenttimetriä (sq. 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 (g/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.

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

Area = 4 jalat x 8 feet = 32 square feet ≈ 2.97 square meters
Volyymi = 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
So, this 2mm thick 4×8 aluminum plate weighs about 1,604.2 grams, or about 1.6 kilograms.
