We need to calculate the weight of a 4×8 fel of aluminum plate with a thickness of 1/8 inch.
First, we need to know the density of aluminum and how its thickness affects its volume.

The relationship between the mass (m) and volume (V) of an object can be expressed by the following mathematical formula:
m = ρ × V
where ρ (rho) is the density of the object, which describes the mass per unit volume of the object.
The density of aluminum is approximately 2.7g/cm^3.
And 1 inch = 2.54 cm, sa 1/8 inch = 0.3175 cm.

The volume of the aluminum plate can be calculated by the following formula:
V = length × width × thickness = 4cm × 8cm × 0.3175cm
Substituting this volume and the density of aluminum into the mass formula, we can get the weight of the aluminum plate.

The calculation result is: the weight of the aluminum plate is 35.28 grams.
Dêrom, a 4×8 sheet of aluminum plate with a thickness of 1/8 inch weighs 35.28 grams.

4×8 aluminum sheet is the most commonly used one. If you want to purchase and know the 4×8 blêd fan 1/8 inch aluminum price, I will give you a detailed quotation.
