Answer:

384 cm^2

Explanation:

Start with the prism (I multiply by 2 because some of the surfaces are more of):

  • 4×15×2=120
  • 6×15×2=180
  • 6×4=24

The Triangular Prism (I divide by 2 because it is a triangle shape on the sides):

  • 3×4/2*2=12
  • 3×6=18
  • 6×5=30

The Last Step (adding everything):

120+180+24+12+18+30=384
