Regular pentagonal prism
A regular pentagonal prism is a three-dimensional geometric shape that has two identical pentagonal bases and five rectangular faces. The following information can be used to calculate the surface area and volume of a regular pentagonal prism:
- Side length of the pentagon base (l)
- Height of the pentagonal prism (h)
Formula for Surface Area: The surface area of a regular pentagonal prism can be calculated using the following formula:
A = 5 × l × h + 2 × (5/2 × l × s)
Where: A = Surface area of the pentagonal prism l = Length of one side of the pentagon base h = Height of the pentagonal prism s = Slant height of the pentagonal base, which can be calculated using the formula: s = l / (2 × sin(π/5))
Formula for Volume: The volume of a regular pentagonal prism can be calculated using the following formula:
V = (5/4) × l² × h × tan(π/5)
Where: V = Volume of the pentagonal prism l = Length of one side of the pentagon base h = Height of the pentagonal prism
Steps to Calculate Surface Area and Volume:
- Calculate the slant height of the pentagonal base using the formula: s = l / (2 × sin(π/5))
- Calculate the surface area of the pentagonal prism using the formula: A = 5 × l × h + 2 × (5/2 × l × s)
- Calculate the volume of the pentagonal prism using the formula: V = (5/4) × l² × h × tan(π/5)
Note: π represents the mathematical constant pi, which is approximately equal to 3.14159.
