Answer:
Option 4. Perimeter = 30 units
Step-by-step explanation:
Since the volume of a pentagonal prism is 840 cubic units.
Perpendicular distance between the bases = 14 units
We know volume of a pentagonal prism = Area of base × distance between the bases
840 = Area × 14
Area = 840/14 = 60 square units
Now area of a pentagon
Therefore perimeter of the pentagon = 5×a = 5×5.91 = 29.54 ≈ 30 units
For this case we must write as a percentage the following expression:
Dividing we have to:
Now we multiply by 100%. So:
We run the decimal two spaces to the right, finally we have:
84%
Answer:
84%
