Three 1 by 1 by 1 cubes are joined side by side, as shown. What is the surface area of the resulting prism?
(A) 13
(B) 14
(C) 15
(D) 16
(E) 17
When three $1 \times 1 \times 1$ cubes are joined together as in the diagram, the resulting prism is $3 \times 1 \times 1$. This prism has four rectangular faces that are $3 \times 1$ and two rectangular faces that are $1 \times 1$. Therefore, the surface area is $4 \times(3 \times 1)+2 \times(1 \times 1)=4 \times 3+2 \times 1=12+2=14$.

ANSWER: (B)
