Solution: V=a^3=3=0.5^3=0.125
so your answer is 0.13, hope this helps!
Answer: B: 41, C: 68, D: 71.
Step-by-step explanation: A triangle's angles have to add up to 180 degrees for it to be considered a triangle. If you were to add up 71, 41, and 68, then it would equal 180 degrees. This means that out of all the other measurements, these are the three possible angle measures that can be used to make a triangle.
(I figured this out by taking 3 random sides from the list there and adding them up to see if they equal 180.)
So I hope this helps and is exactly what you are looking for
The height of the envelope is 10. This is because you divide the area by 3. So, the missing side is 10 inches.
