The pressure produced by a cube with a long edge of 10 cm on the horizontal surface of the table is equal to 2700Pa Determine the weight of the cube

The pressure of the cube on the surface of the table is the ratio of the force with which the mass of the cube presses on the table to the value of the area of the base of the cube.
P = F / S, where P is the value of the pressure of the cube on the table surface (P = 2700 Pa); F is the force of pressure (F = Ft (weight of the cube)), S is the area of the base of the cube (S = a ^ 2, where a is the length of the edge of the cube (a = 10 cm = 0.1 m)).
Let’s express and calculate the weight of the cube:
F = P * S = P * a ^ 2 = 2700 * 0.1 ^ 2 = 2700 * 0.01 = 27 N.
Answer: The weight of the cube is 27 N.
