Answer: 349 square units

============================================

Work Shown:

  • L = 5.5 = length
  • W = 5 = width
  • H = 14 = height

SA = surface area of rectangular prism

SA = 2*(L*W + L*H + W*H)

SA = 2*(5.5*5 + 5.5*14 + 5*14)

SA = 2*(27.5 + 77 + 70)

SA = 2*(174.5)

SA = 349

The surface area is 349 square units.
