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. $\qquad\textbf{(C)}\ [5]$
