| Given:

a = 10 meters – the length of the slab (marble);

b = 0.8 meters – the width of the marble slab;

c = 0.1 meter – the height of the marble slab;

ro = 2700 kg / m3 – density of marble (tabular value).

You want to determine m (kilogram) – the mass of the marble slab.

Assuming that the slab has the geometric shape of a rectangular parallelepiped, we find its volume:

V = a * b * c = 10 * 0.8 * 0.1 = 8 * 0.1 = 0.8 m3.

Then, to determine the mass of the slab, you must use the following formula:

m = ro * V = 2700 * 0.8 = 2160 kilograms.

Answer: the mass of the slab is 2160 kilograms.
