help with functions: Express volume of box as function of...

[whizkid]

:?: I'm starting to understand functions but am still confused. For example:

The volume of a box with a square bottom is A (10). Express as a function of the length of one of the sides of the bottom.

I came up with w(width) x w(width) x H for height = 10. Then I isolated for H and got H = w squared divided by 10.

But then this doesn't look right f(x) = x squared times x squared divided by 10. And this is hard to read but I don't know how to make it easier.

Can someone please help - where am I messing up? thank you!

... this is hard to read ...

no kidding.

it sounds like you are making x = length of one side of the square bottom

you state the volume is "A(10)" ... that would be V = (x²)(10) = 10x² if A represents the area of the square bottom.
