The marble obelisk has the shape of a parallelepiped with a length and width of 22 m

The marble obelisk has the shape of a parallelepiped with a length and width of 22 m and a height of 55 m. Determine the mass of the obelisk. The density of marble is 2.7 g / cm3.

Reference data: 1) ρ (density of marble) = 2.7 g / cm ^ 3 = 2700 kg / m ^ 3;

The volume of the marble obelisk: V = a (22 m) * b (22 m) * c (55 m) = 22 * 22 * 55 = 26620 m ^ 3.

The mass of the marble obelisk: m = ρ * V = 2700 * 26620 = 71 874 000 kg = 71 874 tons.
