Different types of Slabs :1. Conventional solid slab:-- the slab which is braced with beams and columns is called conventional slab this kind of slab is small whereas the depth of the beam is large and load is transferred to beams and from beams to columns. These types of slabs are used in constructing Floors of multi stored building. It is of two types.a) One-way Slab.b) Two Way Slab.2. Flat Slab:-Flat slab is a reinforced concrete slab secured directly by concrete columns or caps .flat slab doesn’t have beams.3. Waffle slab:- Waffle slab is a reinforced concrete roof or floor containing square grids with deep sides. This kind of slab is majorly used at entrance hotels, malls, restaurants
as per ACI , the ratio between column & beam concrete grades dont exceed 1.4
A bag of Quickcrete weighs 80 lbs dry. When water is added it can weigh another 1.5 to 2 lbs. when the water evaporates it will sill retain some water; so, about 80.5 lbs. The Quickcrete covers 1/2 cu ft. or 2 sq. ft. @ 3" thick. 21X20= 420 sq ft X 40.25= 16,905 lbs. or there abouts.
2" based strictly on the slab thickness. However, it may be governed by form spacing, rebar spacing or rebar clearance to the forms.
About 1/2 cubic yard will be enough.

1.25 cubic yards for a 4-inch slab. 2 cubic yards (1.85) for a 6-inch slab.
If the 6 is meant to be inches (= 1/2 ft.) then: 8 ft. x 24 ft. x 1/2 ft. = 96 cu.ft. concrete.
4824 -5544 pounds.
if l/b ratio<2 then it is one way slab3
