Cross section times length

Cubic feet = length in feet × width in feet × height in feet. Six inches is 0.5 feet, so 10 × 0.5 × 0.5 = 2.5. Bags are that volume divided by 0.60, rounded up. A driveway pad next to the curb is concrete. Asphalt in tons is asphalt.

FAQ

How much concrete for a curb?

Ten feet of a 6 by 6 inch curb is 2.5 cubic feet, which is 0.093 cubic yards and 5 bags of 80 lb. A gutter beside the curb is extra section. Add that width and height, or run the length twice and add the sheets.

Is this the same as a slab?

No. A slab is an area times a thickness. A curb is a long, small cross section. The concrete page is the pad. This page is the curb.
