How much does a 4×8 18 gauge aluminum sheet weight?

To calculate the weight of a 4×8 foot sheet of 18-gauge aluminum, you can use the following formula:

重さ (in pounds) = Area (in square feet) x Thickness (in inches) x Density (in pounds per cubic inch)

Here’s how you can apply this formula to your 4×8 18-ゲージアルミシート:

Calculate the Area:

A 4×8 foot sheet has an area of 4 × 8 = 32 square feet.
Determine the Thickness:

18-gauge aluminum is approximately 0.0403 inches thick. You may want to double-check this measurement for accuracy.
Find the Density:

The density of aluminum is about 0.098 ポンド/立方インチ (ポンド/インチ3).
今, plug these values into the formula:

重さ (in pounds) = 32 square feet x 0.0403 inches x 0.098 ポンド/インチ3

Calculate the result:

Weight ≈ 0.127 ポンド

So, a 4×8 foot sheet of 18-gauge aluminum weighs approximately 0.127 ポンド, or about 2.04 ounces.
