Answer 1

450 N

Explanation:

Since you have the VOLUME and the HEIGHT of the prism, you can calculate the AREA of the prism base :

18 m^3 / 3 m = 6 m^2 area

Now you are given pressure = force / area

75 n/m^2 = force / 6 m^2

6 *75 = force = 450 N

Answer 2

450 newtons

Explanation:

To solve for the force, we first need to find the area. (Force = Pressure × Area)

`Area = (volume)/(height) = (18m^(3) )/(3m) = 6m^(2)`

Now we just substitute this number into
`Force = Pressure * Area` and get that
`Force = 75newtons/m^(2) * 6m^(2) = 450 newtons`

(p.s. Units are very important! This question doesn't require any unit

conversions, but others might.)
