Answer :
The perimeter of the base of the right pentagonal prism is 30 units
How to determine the perimeter of the base?
The given parameters are:
- Volume = 840 cubic units
- Height, h = 14 units
- Apothem, a = 4 units
The volume of a right pentagonal prism is:
V = 0.5Pah
Where P represents the perimeter of the base.
So, we have:
0.5 * P * 14 * 4 = 840
Divide both sides by 0.5 * 14 * 4
P = 30
Hence, the perimeter of the base is 30 units
