The math for a 8x10 shed base

Area: 8 × 10 = 80 sq ft.
Depth in feet: 4 ÷ 12 = 0.333 ft.
Cubic feet: 80 × 0.333 = 26.7 cu ft.
Cubic yards: ÷ 27 = 0.99 yd³.
Tons: × 1.35 = 1.3 tons.

The volume and tonnage calculator does this for any size.

About #57 stone

#57 stone is a clean crushed stone in roughly the 1/2 to 1 inch range with very few fines. It drains fast, which suits drainage layers and the top of a gravel drive, but it does not pack into a hard crust by itself. If the yard sells by the cubic yard instead of the ton, use the cubic-yard column directly.

Preparing the shed base

Level the footprint, extend the stone a foot or so beyond the shed walls for drip and drainage, and compact in lifts. A timber or block border holds the pad shape. This shed base sees a shed floor frame, so match the depth to that load rather than to the minimum.

Ordering tips

Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
Delivery size. 1.5 tons fits in a single typical dump truck load; small loads may carry a delivery fee. See how many tons of gravel in a dump truck.
Bulk vs bags. At about 1.3 tons this job is small enough that bagged material could work; a 0.5 cubic foot bag holds about 1/54 of a yard, so compare the bag count with a bulk minimum.
Where it drops. Have the truck dump as close to the shed base as firm ground allows.

Good and poor uses for #57 stone

Best suited to:

French drains and drainage layers
The top course of a gravel driveway
Under sheds where water needs to drain away

Less suited to:

A standalone base, since it does not pack hard without fines
Paver setting beds
Walk paths meant for strollers or wheelchairs

Quick reference numbers

Per inch over 100 sq ft: about 0.42 tons of #57 stone (0.31 cubic yards).
Per inch over 1,000 sq ft: about 4.2 tons.
Another size for comparison: a 15x30 area at 4 inches takes about 7.5 tons.
Weight used here: about 1.35 tons per cubic yard.

Common estimating mistakes

Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
