A 20 cm thick concrete slab rests on the floor. How much pressure does the concrete slab produce on the floor?

To find the amount of pressure created by the specified concrete slab on the floor, we use the formula: P = F / S = m * g / S = ρb * V * g / S = ρb * S * h * g / S = ρb * h * g …

Variables and constants: ρb – density of concrete, slab (by condition we take ρb = 2.35 g / cm3 = 2350 kg / m3); h is the thickness of the indicated slab (h = 20 cm = 0.2 m); g – acceleration due to gravity (g ≈ 9.8 m / s2).

Calculation: P = ρb * h * g = 2350 * 0.2 * 9.8 = 4606 Pa.

Answer: The pressure created by the specified concrete slab is 4600 Pa.
