Kameron is using the formual to find surface area:
SA = 2B + Ph
SA = 2(6) + (7+7+2)9
Finish this for him...

• SA = 2(6) + (14)9
  SA= 8 + 23
  SA = 31 cm²
• SA = 2(6) + (16)9
  SA= 8 + 25
  SA = 33 cm²
• SA = 2(6) + (16)9
  SA= 12 + 144
  SA = 78 cm²
• SA = 2(6) + (16)9
  SA= 12 + 144
  SA = 156 cm²
