The weight of a 1/8 inch thick aluminum sheet depends on its dimensions (length and width) and the specific alloy of the aluminum.

Assuming the dimensions of the sheet are 4 feet by 8 pies (o 48 inches by 96 Pulgadas), the weight of a 1/8 inch thick aluminum sheet would be approximately 35.6 Libras.

This calculation is based on the density of aluminum, which is 0.098 libras ya pulgada cúbica, and the dimensions of the sheet. 'Ñotho ar embargo, the actual weight may vary slightly based on the specific alloy of the aluminum.
