We need to calculate the weight of a 4×8 Folha of aluminum plate with a thickness of 1/8 polegada.
Primeiro, precisamos saber a densidade do alumínio e como sua espessura afeta seu volume.

A relação entre a massa (eu) e volume (V) de um objeto pode ser expresso pela seguinte fórmula matemática:
m = ρ × V
where ρ (ró) é a densidade do objeto, which describes the mass per unit volume of the object.
The density of aluminum is approximately 2.7g/cm^3.
And 1 polegada = 2.54 cm, tão 1/8 polegada = 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.
Portanto, 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 folha de 1/8 preço de alumínio em polegadas, I will give you a detailed quotation.
