Answer:
SA= 341.664
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
