Question

A brick is 15cm long ,10cm wide and 5cm thick has a mass of 800g Determine the greastest pressure that can be exerted by the brick on a surface the least pressure thet can be exerted by the brick on a flat surface

Answer 1

Answer:

Converting the units from cm to m, we have the dimensions as-

15 cm= 0.15 m

10 cm= 0.1 m

5 cm= 0.05 m

Area in contact with ground = 0.15 x 0.1 x  0.05

                                               =0.00575 m²

We know that, Pressure = Force/Area

                                         16/0.032     =   500 N/m²  = 500Pa
