I reallyneed help with either one of these optimization pbs!

For this problem:

A piece of cardboard measures 10 by 15 in. Two equal squares are removed from the corners of a 10 in side. Two equal rectangles are removed from the other corners so that the tabs can be folded to form a rectangular box lid.

a) find domain of V and graph V over this domain
b) find maximum volume and x value


-------------------------------------------------------

I know that the formula for the volume of a box is l*w*h, but dunno what to plug in to those and dunno what to do for the domain...i DID draw the picture for this problem but I am still very stuck.





thank you sooo much! :wink:

Your question refers to "V", but your exercise, as posted, makes no mention of this.

Please reply with the full text of the exercise, including the instructions, and providing a detailed description of the associated graphic, so we can understand what is supposed to be done with the cardboard.

Thank you.
