To find the surface you need to say; 
2 (lw + lh + wh)
Where, l=length, h=height, and w=width.
2 (86 + 810 + 610) = 376
Your answer is therefore, 376 in.2

Have a nice day :D

Answer:

Option B, 376 in²

Step-by-step explanation:

Casey wants to wrap a gift that measures 8 inches by 6 inches by 10 inches.

As we know the surface area of a rectangle given by

Surface area = 2( l × b + b × h + h × l )

when l = length of the rectangle

         b = width of the rectangle

         h = height of the rectangle

Now we put the values in the formula

Surface area = 2[8×6 + 6×10 + 8×10]

                     = 2[48 + 60 + 80]

                     = 2 [188]

                     = 376 in²

Option B is the answer.
