We need to calculate the weight of a 4×8 fulla of aluminum plate with a thickness of 1/8 polzada.
Primer, hem de conèixer la densitat de l'alumini i com afecta el seu gruix al seu volum.

La relació entre la massa (m) i volum (V) d'un objecte es pot expressar amb la següent fórmula matemàtica:
m = ρ × V
where ρ (rho) és la densitat de l'objecte, which describes the mass per unit volume of the object.
The density of aluminum is approximately 2.7g/cm^3.
And 1 polzada = 2.54 cm, doncs 1/8 polzada = 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.
Per tant, 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 full de 1/8 preu d'alumini de polzades, I will give you a detailed quotation.
