Answer 1

40N

Step-by-step explanation:

Answer 2

Weight = 40N

Step-by-step explanation:

The data we have is

Pressure:
`P=20Pa`

Area:
`A=2m^2`

we need to find the wight of the solid, in this case the weight is equal to the force that the solid is exerting on the surface, so using the equation for pressure:

`P=(F)/(A)`

and clearing for F which is the force on the surface (weight):

`F=P*A`

substituting known values:

`F=(20Pa)(2m^2)\\F=40N`

and thus this is also the weight of the solid:

`Weight=40N`
