In order to find  the total surface area of the rectangular prism shown below, John used this formula S=10(2) + 2(6).Is he correct? Justify your reasoning.

• No, he is incorrect because the height of the prism is 6, and the area of the base is 6

• No, he isn’t correct because the area of the base is 12

• Yes, he is correct because the perimer of the base is 10, the height is 2, and the area of the base is 6 

• Yes, he is correct because the perimeter of the base is 16, the height is 3, and the area of the base is 12
