SA = 2*(LW + LH + WH)


SA = 2*(24*14 + 24*11 + 14*11)


SA = 2*(336 + 264 + 154)


SA = 2*(754)


SA = 1508


So the surface area of the rectangular prism is 1508 square inches.

Keep in mind that you have to convert everything to the same unit of measure. So that's why I converted the length of 2 ft to 2*12 = 24 inches.
