From: Beth, a parent Hi....I am trying to figure out how much sand I will need for ground cover under my children's playset. The area to cover is 30' x 30' and I want 4 inches of sand. Please help.....I've asked all of my kids and none of them can help me...... |

Hi Beth, Building supply agencies sell sand in "yards" by which they mean cubic yards. Thus you need to calculate the volume using yards. There are 3 feet in a yard and 12 inches in a foot so your dimensions, in yards are:
 ( 1y/3f ) = 10 yards on each side. The depth is 4 inches ( 1f/12in ) ( 1y/3f ) = 1/9 yard deep.
Thus the volume is: 10 So you should probably order about 11 "yards" of sand. Penny [Thank you to our alert reader Kevin, who identified an error in the original version of this quandary!] |
11.1 cubic yards.  |
