Answer:
B. 3a
Step-by-step explanation:
The answer is B. 10 vertices because it all depends on the edges. You have to subtract the edges by faces/vertices to get your faces/vertices so 20-12 is 10 so you are correct
2.35S+1.5H=total
2.35S=14.1
1.5H=1.25
So 14.1+1.25=15.35
This may not be completely correct as I am not used to using kilograms and grams.
Answer:
(SA - 2s^2)/4s
Step-by-step explanation:
Assuming you mean 2s^2
SA = 2s^2 + 4sh
4sh = SA - 2s^2
h = (SA - 2s^2)/4s
That would be (128 * 100) / 22.7 = 563.88 %
