Answer:

SA= 341.664

Step-by-step explanation:

1. this is the equation to find the surface area of a cuboid (flakes box):

SA=2lw+2lh+2hw

  • l= length , w= width , h= height
  • l= 3.10 , w= 7.77 , h= 13.50

2. replace letters by numbers:

SA= 2(3.10)(7.77) + 2(3.10)(13.50) + 2(13.50)(7.77)

3. simplify:

SA= 48.174 + 83.7 + 209.79

4. add:

SA= 341.664
