The volume of a box is calculated by V = length times width times height. The volume of the box is V=(18)(20)(6). The volume of the larger box is V=(18+x)(20+x)(6+x) where x represents the increase for each edge. The inequality needed to be solved to find x is:
Graphing the polynomial, the only x-intercept is at x=4.
The dimensions of the larger box are: 18+4=22, 20+4=24, and 6+4=10.
22 cm, 24 cm, and 10 cm.
