3 ft x 3ft x 2.25 ft = 20.25 cu ft = 0.75 yards Note: this is the theoretical volume and not the effective one. You have to consider the nature of soil to establish the bucket fill factor: ex light soil you have an overload, so you multiply x 110%, heavy soil x 95%, roc x 85%, etc.
There is about 2800lbs in 2 yards of top soil.

to figure yards of soil you need cubic feet ( 400 sq ft X how deep??)then divide by 9
Legally, it's usually around

Bulk soil units are cubic yards.
To cover that area to that depth - you would need just under 8 cubic yards of soil.
1.5 divided by the volume of your bag in cubic yards. 40.5 divided by the volume of your bag in cubic feet.

i believe a tri axlw will hold about 14 yards of top soil A Tri-Axle will hold up to20 - 25 yards of soil depending on weight. A Tandem will hold about 14 - 17 yards of soil. Tri-axle can hold about 30 yards of mulch. How much it will hold, depends on the size of the box. I can 'legally' load 20 yds of 'pit-run' (gravel) in a 24 foot tandem trailer (in my province).
The number of cubic yards that quint axle end dump truck could hold depends on the relative weight of the soil. Generally, soil weighs 2,000 to 2,700 pounds per yard. Since the capacity on the rear axles may be as much as 50,000 pounds, about 20 to 20 yards of soil could be carried by this type of truck.
