    Constructing a Box

    Hey guys, I'm having a little trouble with this pre-calc lab. If you guys could point me in the right direction, or help me at all, I would greatly appreciate it.

    An open box is formed by cutting squares from the corners of a 12 inch by 15 inch piece of cardboard and folding up the flaps.


    a) Draw a figure that represents this situation.


    b) What size corner squares should be cut to make a box with a volume of 125 in.^3?


    c) What size corner squares should be cut to make a box with a volume of more than 125 in.^3?


    d) What size corner squares should be cut to make a box with a volume of at most 125 in.^3?


    Thanks for your help in advance!
