Question

A cube of side 0.2 m rests on the floor. Given that the cube has a weight of 50 N. What
is the pressure exerted by the cube on the floor? (take g = 10 N kg-1). Calculate the
pressure exerted by the cube on the floor.​

Answer 1

Given

• side of cube = 0.2 metre
• Weight = 50 N

To find

• pressure exerted by the cube on the floor.

Concept used

Here the concept of Pressure is used . The side and the weight of cube is given. First we will find the area then will simply put the value in pressure formula to get the required answer.

Solution

$\bold{ \red{Area = a²}}$

$\sf{ \implies area= (0.2)²}\\ \\ \sf{ \implies area = 0.04m²}$

Formula of pressure is given as :-

$\bold{ \pink {Pressure= \frac{weight}{Area}}}$

$\sf{ \implies Pressure= \frac{50}{0.04} }\\ \\ \sf{ \implies \green{Pressure = 1250 N/m²}}$

Therefore the pressure is 1250 N/m²
