I'm in the process of estimating a topsoil Install. We have 20,000 sq ft. of area. The existing site is preped and graded. We just have to install 3-4" of Topsoil to surface. Can anybody please guide me in the correct direction, I never did an estimate this large.

Thank you

Kurt

300-400 yds of topsoil.

length x width x depth divided by 27 = yards needed

what? how did u arrive at that? lets say u need to do a 10 x 10 area, 2 inches deep. i know u need i yd to do this. using your formula, u would go 10x10 x 2 divided by 27 =more than 7 yds? tell me how this formula works

I go by this
2" deep, 1 yd covers 162 sq. ft
3" deep, 1 yd covers 108 sq ft.
4 " deep, 1 yd covers 81 sq ft.

basic formula is 36 divided by # of inches = ?

Thats because you are multiplying it by 2 ft instead of 2 inches

10ftx10ftx.1666ft/27=.617yrds topsoil

The formula that little guy uses is correct, and the one that I use.

My math is pretty close to bobby's

ncsu, now i see, thanks. but i still think a 10x10 area(100 sq ft) requires one yd at 2 inches deep. i do all my topsoil like this, it works out perfect.

simply divide sq ft by 162 for a 2" cover, divide by 81 for a 4" cover and so on and so on; 20000 sq ft divided by 81 equals 246 yards
