C, 312[tex] in^{2} [/tex] 

You find this my doing the formula Ph, which is the perimeter of the base times the height.

With that, you add 7+7+6+6 times 12. (so, 26 times 12) and you get 312.
[tex]the\ lateral\ area:\\\\2\ rectangles\ 6in\ \times\ 12in\ and\ 2\ rectangles\ 7in\ \times\ 12in\\\\A_l=2\cdot6\cdot12+2\cdot7\cdot12=144+168=312\ (in^2)\\\\Answer:C[/tex]
