C, 312 i n 2
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.

To find the lateral area of a rectangular prism, use the formula A l ​ = 2 h ( l + w ) . For example dimensions provided in the question assumed varied outputs that could ultimately yield (C) 312 in². It's essential to clarify dimensions used to ensure matching results for lateral area appropriately towards the options given.
