. . . requiring brilliant mathematician.

I'm going to be ordering a load of topsoil for a strip of land in my front yard next to my drive way and I need some help figuring out how much I need.

Throughout the years I've been robbing dirt form this area for other parts of the yard and now I want to fill it back in so that it's the same elevation as the adjacent driveway.

The area is a perfect rectangle measuring 270 inches long by 70 inches wide by 10 inches deep. That's 270"L x 70"W x 10"D or (686cm L x 178cm W x 26cm D).

I think the guys at the landscape supply sell the dirt by the "yard", but I don't know if they're talking about square yards or what.

A yard of dirt is 27 cubic feet (1,728 cubic inches) equivalent to 3'x3'x3'.

Your hole is 189,000 cubic inches. If my math is right, you should need about 110 yards of dirt. That's a lot of dirt!!

EDIT: I messed up the cubic inches... it's actually 46,656 cubic inches... which will mean you would need just over 4 yards. which makes much more sense...

A cubic yard = 36" by 36" by 36" = 46656 cubic inches

Your hole = 270" by 70" by 10" = 189000 cubic inches,

Thus 189000/46656 = 4.051 cubic yards

It was in decimal, so I couldn't help. I think only in other bases.

Having just bought several yards of mulch, you will also need a large pickup or a place that delivers

A full size pickup with an 8' bed can probably do 3 yards.
We could get 2 yards in my brothers dakota pickup with the 6' bed.

4x8x2=64' Roughly the size of the pickup
3x3x3=27' one yard
So 3 yards would be 81', but figure you can mound the dirt in the middle.

You might need to make 2 trips.

Better make it five yards; the dirt will settle and needs to be compacted anyways.

one problem. most pickup trucks can only handle 1 cubic yard of soil because any more is to heavy truck.

Also I might like to add that the measurement for your area is going to be compacted and soil is sold as loose cubic yards. So you have about 4 cubic yards of volume to fill. So you will need about 5.33 loose cubic yards of soil. So I would recommend you get 6 cubic yards of soil.
