Answer:

272 square inches

Explanation:

Given


l = 8 --- length


w = 2 --- width


h = 12 ---- height

Required

Determine the total surface area (SA)

This is calculated using:


SA = 2 * (lw + wh + lh)


SA = 2 * (8*2+2*12+8*12)


SA = 2 * 136


SA = 272

The total surface area is 272 square inches
