Add whole numbers: 2 + 6 + 8 = 16
Add fractions:
= 1/3 + 3/4 + 1/2
= (8 + 18 + 12) ÷ 24
= 38/24 or 1 14/24 or simplified to 1 7/12
Total surface area = 16 + 1 7/12 or 17 7/12

Answer:
   12 units
Step-by-step explanation:
Point H is the intersection of the medians, so divides each median into parts with the ratio 2:1. Here, that is ...
   CH : HG = 2 : 1 = CH : 6
Then CH = 2×6 = 12.
_____
Alternatively, you could determine altitude CG from the Pythagorean theorem applied to triangle BCG. You would compute ...
   CG² +GB² = BC²
   CG = √(BC² -GB²) = √(19.8² -8²) = √146.7 ≈ 12.1
This is an approximation based on the fact that the value 9.9 for BF is an approximation. Based on BG and GH being integer values, the appropriate measure of BF is (√388)/2 ≈ 9.8489. 
(The triangle shown cannot exist.)
