Answer:

pressure= 2000 Pa

Step-by-step explanation:

pressure= force/area

ρ=
(F)/(A)

We don't have the force but we know that force and weight are the same things as they have the same unit.

weight= mass × gravitational force (gravitational force is constant at the value 10)

w= 2 × 10

w = 20N

So force= 20N

To find the area of the portion of the cube:

= 10 × 10

= 100 cm²

we should convert this to m²

100/10000

= 0.01 m²

ρ=
(20)/(0.01)

ρ= 2000 Pa

Pressure= 2000 Pa
