To measure the weight of a 4×8 aluminum plate with a thickness of 2mm, it can be calculated by the following steps:

Calculate the area: First, convert the dimensions of the 4×8 aluminum sheet to square meters (or square centimeters, depending on which units you are used to). For a 4×8 សន្លឹកអាលុយមីញ៉ូមជើង, the area can be expressed in square feet (sq. ft.), which can then be converted to square meters (sq. m) or square centimeters (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.

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

តំបន់ = 4 ជើង x 8 feet = 32 square feet ≈ 2.97 square meters
Volume = 2.97 square meters x 0.2 cm (2 mm to cm) = 0.594 cubic meters
ទំងន់ = 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.
