278 sq. units
136 sq. units
176 sq. units
587 sq. units

Answer: 136 units squared

Step-by-step explanation:

I will assume this is a rectangular prism since it isn't specified.

The surface area of a rectangular prism: SA = 2(lw+lh+wh).

Plugging in your dimensions: SA = 2(7*2 + 7*6 + 2*6) = 2(14+42+12) = 2(68) = 136 units squared.
