To repair a masonry foundation wall, if a trench is 5 feet wide and 60 feet long, how many cubic yards will be excavated?

To determine the volume of a trench that will be excavated, you can use the formula for volume, which is length × width × depth. In this scenario, the dimensions of the trench are provided as 5 feet in width and 60 feet in length. However, the depth needs to be specified to calculate the total volume accurately.

Assuming that the trench is to be excavated to a standard depth needed for a masonry foundation (such as 3 feet, though this could vary based on local building codes or project specifications), the calculation would be as follows:

1. Convert the dimensions to cubic feet:

• Length of the trench: 60 feet

• Width of the trench: 5 feet

• Depth of the trench (hypothetical): 3 feet

2. Calculate the volume in cubic feet:

Volume = Length × Width × Depth

Volume = 60 ft × 5 ft × 3 ft = 900 cubic feet

3. Convert cubic feet to cubic yards:

Since there are 27 cubic feet in a cubic yard (3 feet x 3 feet x 3 feet),

Volume in cubic yards = 900 cubic feet ÷ 27 cubic feet/cubic yard
