The believe the answer is m=9.
Answer:
D
Step-by-step explanation:
SA = bh + (s1 + s2 + s3)H is the formula to find out the surface area
b is base, h is height (small height), s's are the sides, H is the height (longer one)
SA = 12(9) + (10 + 10 + 12)32
SA = 108 + (32)32
SA = 108 + 1024
SA = 1132
Divide both sides by eight
It’s 14.
The five numbers will be: 12, 13, 14, 15, and 17 so 14 is the median.
