Answer:
436
Step-by-step explanation:
A rectangular prism is made up of 3 pairs of rectangles. In this case, one pair has dimensions of 4 by 9, another pair has dimensions of 4 by 14, and the last pair has dimensions of 9 by 14. The surface area of this rectangular prism is therefore:
2(4*9)+2(4*14)+2(9*14)=72+112+252=436 square inches
