To cover that area to that depth - you would need just under 8 cubic yards of soil.

5' * 3' * 2' = 30 cubic feet = 30/(3*3*3) cubic yards = 1.11... cubic yards.

1 yard = 3 feet 12 inches = 1 foot 16 ft * 1yd/3 ft * 3ft * 1yd/3ft * 3 inches * 1ft/12inches * 1yd/3feet = 0.444 cubic yards
Volume = (12' x 6' x 1') = 72 cubic feet = 22/3 cubic yards

There is about 2800lbs in 2 yards of top soil.
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).
Well, you know the sqft of the area is ft2, and you need it 4 in. deep. You multiply 600x4=2400sqft of soil needed.
5' * 3' * 2' = 30 cubic feet = 30/(3*3*3) cubic yards = 1.11... cubic yards.

1 yard = 3 feet 12 inches = 1 foot 16 ft * 1yd/3 ft * 3ft * 1yd/3ft * 3 inches * 1ft/12inches * 1yd/3feet = 0.444 cubic yards
To calculate the amount of soil needed, you multiply the area by the desired depth. In this case, you have 9300 square feet and want a depth of 12 inches. Convert the depth to feet (12 inches = 1 foot) and multiply: 9300 square feet x 1 foot = 9300 cubic feet of soil. So, you need 9300 cubic feet of soil to cover the area with a depth of 12 inches.
105 ft * 84 ft * 3 inches = 105/3 yards * 84/3 yards * 3/36 yards = 35 * 28 / 12 cubic yards = 245 cubic yards.
None. A square foot is a measure of area and so has no volume. Since there is no volume, there can be no mass.
