Find the mass of a 5m x 4m x 0.5m concrete slab.

First, the volume of the plate. For this we use the formula: V = abc
In our case:
V = 5m * 4m * 0.5m = 20m * 0.5m = 10m
Now we look at the mass. From it we see that 2500kg m (cube)
Next, we use the mass formula. m = V * p
m = 0 * 2500 = 25000 kg = 25 tons
