#8000"N/m"^2#

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

#V=0.1xx0.1xx0.1=0.001"m"^3#

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#
