Question 142426
describe the combined variation that is modeled by each formula.

V=lwh
-------------------
I've never hear of combined variation but here goes:
V and l, or V and w, or V and h are all directly related;
when one goes up the other goes up.
-----------------------------
l and w, or l and h, or w and h are all indirectly related;
when one goes up in value the other goes down.
