The cuboid and the cube are placed on the floor. The cuboid has a weight of 60N and has an area of 4cm2.
The cube has a weight of 75N and has an area of 5cm2.
Calculate the pressure exerted by both the objects.
You must show your working.

Asubmarine has a "crush depth" (that is, the depth at which water pressure will crush the submarine) of 250 m. what is the approximate pressure (water plus atmospheric) at this depth? (recall that the density of seawater is 1025 kg/m3, g = 9.81 m/s2, and 1 kg/(ms2) = 1 pa = 9.8692 10-6 atm.) a. 34.8 atm b. 24.8 atm c. 25.8 atm d. 7.8 atm
