How do you find the total surface area of a pentagonal prism?
The total surface area of pentagonal prism = 2 × area of the base of pentagonal prism + lateral surface area of the pentagonal prism. Therefore, the total surface area of pentagonal prism = 5ab + 5bh.
How do you find the perimeter of a right pentagonal prism?
The bases are regular pentagons. So the perimeter of one base is 5(54) or 270 in. L = Ph Lateral area of a prism = (270)(75) P = 270, h = 75 = 20,250 Multiply.
How do you find the lateral area of a regular pentagonal pyramid?
Therefore, the formula for the lateral area of the pentagonal pyramid is 1/2 x base one x slant height one + 1/2 x base two x slant height two + 1/2 x base three x slant height three + 1/2 x base four x slant height four + 1/2 x base five x slant height five.

How do you calculate the volume of a pentagonal prism?
The most common calculation made on a pentagonal prism is to find its volume. To find the volume of any prism, you must multiply the area of the base of the prism by its height.
What is the formula for finding the volume of a pentagonal prism?
To find the volume of regular pentagonal prism, first you have to find the apothem length (a). The apothem length is a measure from the centre of a polygon to the midpoint of any side. The formula to find the volume of pentagonal prism is given as. Volume of pentagonal prism= \\(\\frac{5}{2}abh\\) cubic units.
What is the lateral area of a pentagonal prism?
The lateral surface area of a regular pentagonal prism is 360 square feet. The height of the prism is twice the length of one of the edges of the base.
What is a right pentagonal prism?
