Remember volume is just area * height, that's the best way to understand it, that's why we have area which is 2 dimensional then multiply by height and boom 3d! 

Ok and it says your dimensions are multiplied by 4, so we originally have $$V = (6)(4)(2) cm^3$$ but then what does the measured are multiplied by 4 imply?

jaden_davis · Answer

Well, 6 x 4 x 2 = 48 but i don't know where to go from there

astrophysics · Answer

Yeah the wording can be a bit confusing, at first it looks like the dimensions themselves are being multiplied by 4 individually, but I don't think that's right, I believe it's asking for V*4 which is volume multiplied by 4.

astrophysics · Answer

$$V = (6)(4)(2) cm^3 \implies V = 48 cm^3 $$ then $$V  \times 4 = ?$$
