Solving SV(z) = ∫ ρ(z)gdz ~ ρgz

[g0ggs123]

Homework Statement

I just need to use this formula and then apply p = density and I z= depth

Homework Equations

SV(z) = ∫ ρ(z)gdz ~ ρgz

The Attempt at a Solution

(ρ(z)(z)g))/2 and if ~ ρgz is multiple it would be (ρ(z)(z)g))/2 * ρgz which is (ρ(ρ)(z)(z)(z)g(g)))/2

Thanks for your help in advance,

Also not sure what ~ means in this instance??

Is there a question here?

This whole post is incredibly vague.

I agree with post 2, you are not making much sense.
However, the ~ sign means "approximately equal to". If ρ is substantially constant over the range of z then it can be taken out of the integral sign and you get ρgz.
