It depends on the thickness of slab. A yard of cement contains 9 cubic feet. Thus, it would cover 9 square feet if the slab was 1 foot thick. For a 4 inch thick slab, it would cover 3 times as much area, or 27 square feet.
How deep? Are you talking about dry mix weight or finished weight? Concrete weighs 150 pounds per cubic foot. So if you have a 6" slab, that's 150# for 2 square feet. For a 4" slab, the same amount will cover 3 square feet. For a 3" slab, 4 square feet. Concrete mix is commonly sold in 80 pound bags. The finished weight is the mix plus the water that gets chemically bound to it. There's a guide on the bag telling how many bags you need for a given area and thickness.
As it is a marble slab, it could be supposed that the shape is fairly regular. So multiplying length by width will give the square area of the slab. It could be that the square area is not required, and the length and width is needed simply to fit the marble slab into a recess or is to be used as a work-surface , etc. But, either way, a steel tape measure is usually required to measure the marble slab.
Pressure is defined as the following Pressure = force / area. So what this means is pressure is how much force is exerted over a area of given size. For examle a concrete slab is on the floor this slab has a width of 2m and a length of 2 m its area is 2 x 2 which gives 2m Squared. Its force it exerts is 1000 newtons ok what the hell does this mean? if you place this in the formula you will get pressure = 1000/4 Pressure = 250 newtons per square metre. I hope this answers you question on what pressure is.
Cranks are given in the slab according to the change in the BM from negative to positive exactly before column and also to maintian the thickness of slab.
no, welded wires are not powerful, it can be used only where the area of slab is small.
The minimum area of steel required in RCC slab as per BS code is 0.12 to 0.15% of total area. The maximum diameter of bar in slab, shall not exceed D/8, where D is the total thickness of slab.
V of a circular slab = thickness of the slab multiplied by (pi multiplied by the radius2)
A slab of clay usually means rolled out clay. The thickness varies but is generally about a half inch.
Slab thickness is usually 7―" due to mechanical ducts located within the slab. This could be reduced to 6―" if the mechanical ducts are placed in a "bulk head".
The cross sectional area of a slab can be found by squaring the height of the slab.

A concrete slab's thickness can vary greatly depending on the application. Typically, a concrete slab varies between 500mm to thousands of millimeters.
to answer your question, one must know the thickness of the slab? then only the weight can be calculated
A 22x22 foot slab at a 4-inch thickness/depth requires a minimum of 6 cubic yards.
Multiply the length by the breadth. eg if slab is 2 ft by 3 ft then area of slab = 6 sq feet
