Problem

The faces of a cube are painted in six different colors: red $(R)$ , white $(W)$ , green $(G)$ , brown $(B)$ , aqua $(A)$ , and purple $(P)$ . Three views of the cube are shown below. What is the color of the face opposite the aqua face?

$\textbf{(A)}\ \text{red}\qquad\textbf{(B)}\ \text{white}\qquad\textbf{(C)}\ \text{green}\qquad\textbf{(D)}\ \text{brown}\qquad\textbf{(E)}\ \text{purple}$

Solution 1

$B$ is on the top, and $R$ is on the side, and $G$ is on the right side. That means that (image $2$ ) $W$ is on the left side. From the third image, you know that $P$ must be on the bottom since $G$ is sideways. That leaves us with the back, so the back must be $A$ . The front is opposite of the back, so the answer is $\boxed{\textbf{(A)}\ R}$ .

Solution 2

Looking closely we can see that all faces are connected with $R$ except for $A$ . Thus the answer is $\boxed{\textbf{(A)}\ R}$ .
