If using 145 pounds per cubic foot, what would be the weight of a horizontal layer of soil that is 6 feet long, 3 feet wide, and 2 feet deep?

To determine the weight of the horizontal layer of soil, you need to first calculate the volume of the soil in cubic feet. The volume can be calculated by multiplying the length, width, and depth of the soil.

In this case, the calculations would be as follows:

Volume = Length × Width × Depth

Volume = 6 feet × 3 feet × 2 feet

Volume = 36 cubic feet

With the volume known, you can now calculate the weight of the soil by multiplying the volume by the density of the soil, which is given as 145 pounds per cubic foot.

Weight = Volume × Density

Weight = 36 cubic feet × 145 pounds/cubic foot

Weight = 5220 pounds

Thus, the weight of the horizontal layer of soil is 5220 pounds, making this the correct answer. This calculation emphasizes the importance of understanding how to measure density and volume when determining weight in practical applications such as lineman work, which often involves dealing with materials found in construction sites or utility installations.
