Question

calculate the pressure exerted by a cube of side 4 cm and mass 5 kg. (g =10m/sec2)
plzz answer it fast step by step

Answer 1

Mass  of cube = 5 kg

Side of cube = 4 cm = 0.04 m

Area of one side of the cube = 0.04 × 0.04 = 0.0016 m^2

Weight of the cube = mass × gravity

Weight of the cube = 5 × 10 = 50 N

Now, the pressure is defined as the force per unit area.

Hence, the formula is:

$Pressure =\frac{Force}{Area}$

$Pressure = \frac{50}{0.0016}$

Pressure = 31250 Pascals

Hence, the pressure applied by the cube is 31250 Pascals.
