Answer 1

Given,

Mass of cube, m = 50 Kg

side of cube, a = 0.2 m

To Find,

Pressure exerted by the cube on the floor

Solution:

We know,

Area of a side of a cube = a²

==> Area = 0.04 m²

Also,

Pressure = Force/Area

Here, Weight = Force { mgsinθ }

==> Pressure = 50/0.04

==> Pressure = 1250 N/m²

Hence, Option 3 is correct.
