8000"N/m"^28000N/m2

Explanation:

Converting to metres the volume of the cube is given by:

V=0.1xx0.1xx0.1=0.001"m"^3V=0.1×0.1×0.1=0.001m3

The mass of the cube is given by:

Mass = density x volume

:. m=8000xx 0.001=8"kg"

The weight of the block =mg

=8xx10= 80"N"

Pressure = Force/area

The area of one side of the block is:

0.1xx0.1=0.01"m"^2

So the pressure is given by:

P=F/A=80/0.01=8000"N/m"^2
