Question from David:

How many linear yards of material is needed for a square plot of 20 acres by 12 inches deep?

Hi David,

I think you mean cubic yards. Contractors sometimes shorten this to yards but they mean cubic yards.

You can calculate this in two steps without having to do any of the calculations yourself. First go to Google and type 20 acres in square feet into the search window. Google will respond with the number of square feet in 20 acres. Next go to Math Central's volume calculator and input the number you received from Google for the surface area and 12 inches as the depth. Read off the volume in cubic yards.
