Problem

What is the largest number of solid $2$in x$2$in x$1$in blocks that can fit in a $3$-in by $2$ in by $3$in box?

$\textbf{(A)}\ [3]\qquad\textbf{(B)}\ [4]\qquad\textbf{(C)}\ [5]\qquad\textbf{(D)}\ [6]\qquad\textbf{(E)}\ [7]$

Solution

By simply finding the volume of the larger block, we see that its area is $18$. The volume of the smaller block is $4$. Dividing the two, we see that only a maximum of $4$ $2$in x$2$in x$1$in blocks can fit inside a $3$-in by $2$ in by $3$in box. $\qquad\textbf{(C)}\ [5]$
