How many yards of dirt is need to fill a hole 6x6x6?

To calculate the volume of a hole that is 6 feet long, 6 feet wide, and 6 feet deep, you multiply the dimensions: 6 ft x 6 ft x 6 ft = 216 cubic feet. Since there are 27 cubic feet in a cubic yard, you divide 216 by 27, resulting in 8 cubic yards of dirt needed to fill the hole.
