@ryan12345 thanks.. Can you help me with the problem?

Answer 3

At first I was thinking that they just wanted w^3 = p

but that doesnt jive with the sample data 32^3 != 7300
cube of 32 is 32768

so I'm not understanding the question I guess sorry

Answer 4

@kantalope Thanks for trying dude. Yeah Im not sure either I neen to find K
I think its something like L=k/x^2 But thats not working.

Answer 5

If k is some constant p=(w^3)k
p is still varying directly

Answer 6

k is .22 or about a 1/4
