Another volume question need help figuring out!

two fractions that are equal to each other

Answer 3

I'm not sure how to do that... I don't set the two volumes up as a fraction?

Answer 4

yes, actually, make a fraction of the two volumes, then set that equal to the areas, make sure you keep the big on top for both or vice versa

Answer 5

so like 512 mm^3/ 343 mm^ 3 = 192 mm^2/ v2 ... I think?

Answer 6

yep, then solve for what you called v

Answer 7

How do I solve for that? divide the 512 and 343? I don't have an exponent on my calculator.

Answer 8

no, and you don't need exponents. so, the trick with proportions is to use something called cross multiplying check it out here: https://www.khanacademy.org/math/cc-seventh-grade-math/cc-7th-ratio-proportion/cc-7th-constructing-proportions/v/find-an-unknown-in-a-proportion
