Asolid wooden cube is placed on a table. the cube exerts a force of 7 newtons on the table. the pressure on the table is 700 newtons/m2 given that density of the wood is 720 kg/m3 find the mass of the cube

Step-by-step explanation:

Alright, lets get started.

Cube exerts a force of 7 newton.

The pressure on the table due to cube is 700 newtons per square meter.

Formula for pressure =

Plugging the value of pressure and force, we could find the ara, this is surface area of cube which is in contact with table.

So, area =

Hence the surface area of side of cube is

Suppose the side of cube is a, then

Taking square root on both sides

a=

Hence the side of cube is 0.1 m

So. volume of cube will be =

mass=

Plugging the value of density and volume

mass= kg

Hence the mass of the cube is 0.72 kg.   :   Answer
