The weight are force only which acts on the surface area
Hence the force acting on 10m^2 is 100 N
and that on 4m^2 is 50 N
F1 = 100 N
A1 = 10m^2
F2 = 50N
A2 = 4m^2
Pressure = Force/Area
P1 = F1/A1
= 100/10
P1 = 10 Pa
P2 = F2/A2
= 50/4
P2 = 12.5 Pa
Hence P2 is Greater than P1

Answer: mass = 100kg
Volume = 10 m
a) density = mass / volume
= m/v
= 100/ 10
= 10pa ans
mass = 50kg
volume = 4m
b) density = mass / volume
= 50 / 4
= 12.5pa ans
Explanation: both are in M.K.S system
