Determine the mass of the marble slab, under which the pirate treasure is buried, if it is known that its length is 2 meters, width is 1 meter, thickness is 50 centimeters. Density of marble 2700kg / m3
Problem data: L (length of the marble slab) = 2 m; B (slab width) = 1 m; s (thickness) = 50 cm (0.5 m).
Reference values: according to the condition ρm (density of marble) = 2700 kg / m3.
The mass of the considered marble slab can be calculated by the formula: m = ρm * V = ρm * L * B * s.
Calculation: m = 2700 * 2 * 1 * 0.5 = 2700 kg (2.7 t).
Answer: The mass of the marble slab under consideration is 2.7 tons.
