The density of a brick is 2 × 10 cubic kilogram per cubic meter, the pressure it can bear is 5 × 10 quintic Pascal, and the length, width and height are 24, 12 and 6cm respectively Ask: 1. Put a brick flat on the ground, how much pressure does the ground receive? 2. What is the maximum height that can be built by using this brick to repair a cylindrical chimney? (g = 10 N / kg)

1.P1=F/S1=G/S1=ρgV/S1=ρgh1=2×10³kg/m³×10N/kg×0.06m=1200Pa
2..h=P/ρg=5×100000Pa/(2×10³kg/m³×10N/kg)=25m
