Asked by Rashmy
A rectangular metal block with side 1.5m, by 1.2 by 1.0 rests a horizontal surface. If the density of metal is 7000kg/m³ calculate
Difference btn maximum and minimum pressure that the block can exert

mass of the block = volume * density
force (weight) = m * g
pressure = force / area ... newton per m^2 is a Pascal
max pressure when resting on smallest side ... 1.2 m x 1.0 m
min pressure when resting on largest side ... 1.2 m x 1.5 m
force (weight) = m * g
pressure = force / area ... newton per m^2 is a Pascal
max pressure when resting on smallest side ... 1.2 m x 1.0 m
min pressure when resting on largest side ... 1.2 m x 1.5 m
