A cubic foot of concrete weighs ABOUT 150 pounds. 4 feet by 12 feet by 4 feet is 192 cubic feet. If you meant 4 feet by 12 feet by 4 INCHES, that would be 16 cubic feet.
About 2.11 Cubic Yards.

It depends on the depth required
At least 3 cubic yards for a 4-inch slab. You'll need 4.75 cubic yards for a 6-inch slab.
1.25 cubic yards for a 4-inch slab. 2 cubic yards (1.85) for a 6-inch slab.

Concrete weighs approx 150 pounds per cubic foot. This slab would weigh approx 1188 pounds.
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)
A 600mm x 600mm x 50mm concrete slab would weigh approximately 108 kg or 238 lbs, assuming a density of concrete around 2,400 kg/m^3 or 150 lbs/ft^3.
Approximatley 9.6 tons based on an average density of 150 pcf

about how much to pour a concrete slaba 12 x 14'
To calculate the weight of a concrete slab, you need to know the volume and the density of concrete. The volume of a 600mm x 600mm x 45mm slab is 0.6m x 0.6m x 0.045m = 0.0162 cubic meters. Given that the density of concrete is approximately 2,400 kg/m³, the weight would be about 38.88 kg (0.0162 m³ x 2,400 kg/m³).
No. Concrete won't bond to concrete. It will end up cracking.
