How Much Topsoil Do I Need!

[sbrown1450]

Just taken up some decking and want to put grass seeds down but first need to put some topsoil down to level the area.
So it measures 11 1/2 feet x 12 1/2 feet and we want the topsoil to be 2 inches deep.
So how much topsoil do we need?

12 x 12 x 1/6 (2") = 24 cubic feet.

They mormally sell topsoil in cubic metres, so that's about 2/3 cubic metre.

//Approx 1.2 sq yards//

You cannot buy topsoil is square yards. It is sold in a cubic measure (usually cubic yards).

So, in feet, 11.5 x 12.5 = 143.75, divided by six (the fraction of a foot of the required depth) = 23.95 cu. feet. Divide by 27 (the number of cu. feet in a cu. yard) =0.88 cu. yards. One cubic yard should do the job.

Lot depends on "how " the people who supply the topsoil trade. You need 41,400 cubic inches. This is 3.030 Cubic Yards. This is 2.31 Cubic Metres. A cubic Metre is 1000 Litres if that is how your supplier calculates it.... so in litres..... 2,310 litres

It's not often I'm right but I'm wrong again!

Haha my cubic inches to cubic yards went earthy.
As Judge says get a cubic Yard or .75 cubic meters or 760 litres.

The chances are they'll sell you a 1 cubic metre bag; you can put the rest on your garden bed.
