Question 989504
<font face="Times New Roman" size="+2">


The volume of the box is the length times the width times the height.  The volume of one of the cans is *[tex \Large \pi{r^2}h], so the volume of all 12 cans is *[tex \Large 12\pi{r^2}h].  Don't forget that you are given the diameter so you have to divide by 2 to find the radius.


Calculate the volume of the box.  Calculate the volume of the 12 cans.  Subtract the volume of the cans from the volume of the box.  The answer is probably best presented as a binomial factor times *[tex \Large x^3]
