10-ft x 30-ft x 4-in = 100 cubic ft.That slab weighs 3.7 times as much as 1 "yard" of concrete. (rounded)

10 cm = 0.1 meterThe volume of the slab is (6 x 8 x 0.1) = 4.8 cubic meters

Depends on the length of the hole.

A two-inch slab is fundamentally unsound because it's not thick enough. So...go with at least a three inch slab. For a 16-foot x 14-foot x 3-inch slab: The slab is 224 square feet. Divide by four and you get 56 cubic feet. Add 10 percent (because the bottom isn't flat) and you come up with 61.6 cubic feet. There are 0.6 cubic feet in an 80-pound bag, so you need 103 bags. Do not do it this way. It will cost you more money and the pour will be weak and look terrible. You need 2-1/2 yards of concrete from a concrete company. If you make the slab 4 inches thick, you will need 3 yards and that's better because concrete companies don't like to deal in half-yard increments.

first we find the surface area of a the slab. formula for surface area of cuboid( the slab) is = 2(lw+wh+hl) length= 10 feet= 10/3 yard width= 10 feet= 10/3 yard height = 3 inch = 3/12 feet = 1/12 yard therefore surface area= 2 (10/3 * 10/3 + 10/3*1/12 + 1/12*10/3) = 2( 100/9 + 10/36 + 10/36) = 2 (400 + 10 + 10 /36) = 2 (420/36) = 420/ 18 ~ 23.33 yard square.
