Side of cube=1o cm=0.1m
Area of plane of cube=side x side=0.01m²
volume of cube=side³=0.001m³
given density=8000kg/m³
density=mass/volume
mass of cube= densityxvolume=8kg
force on the surface of table by iron block=mg=8x10=80N
Pressure=Force/area=80/0.01=8000N/m²

Side = 10cm = 0.1m
volume = 0.1³ = 0.001 m³
density = 8000 kg/m³
mass = 8000×0.001 = 8 kg
weight = 8×10 = 80N
area of base  = 0.1² = 0.01 m²
Pressure = W/A = 80/0.01 = 8000 Pa = 8kPa
