Explanation:
Pressure is defined as a Force over an
Area.
p=F/A
We can rearrange this to make the Force
the subject
F = p *A
The pressure is given as 1200 Pa.
We know a pascal is 1 Newton / Square
metre = N/m²
The area of a cube will be width * breadth
= 1.5 m * 1.5 m= 2.25 m²
So the force the cube is pushing down
with (its weight) is simply
F = p * A = 1200 N/m² * 2.25 m² = 2700 N
Weight is officialy defined as a force
measured in Newtons, but when we
talk about weight we often give it in
Kilograms (a unit of mass).
To get the weight in units of
Kilogram-force you must divide by the
gravitational acceleration =9.81 m/s²
2700 / 9.81 = 275.23 Kg
