They are also known as heptahedrons or five-sided polygon prism. These prisms are characterized by having a total number of 7 faces, 15 edges, and 10 vertices. The bases are connected by five rectangular side faces. These pentagonal bases are congruent and parallel to each other. Thus, the volume of the chocolate box is 7500 cubic cm.Pentagonal Prism is a 3D figure formed by two pentagonal bases. To calculate the volume of a regular pentagonal prism, we use the formula below: Find the volume of a chocolate box shaped as a regular pentagonal prism whose apothem length is 10 cm, base length is 20 cm, and height is 15 cm. Thus, the total surface area of the prism is 600 cubic inches. Plugging the values in the formula for the surface area of a regular pentagonal prism, we get The height of the pentagonal prism is 10 inches (given). The base length of the pentagonal prism is 8 inches (given). The apothem length of the pentagonal prism is 5 inches (given). Find the total surface area of the prism. If the apothem length, base side, and height of a regular pentagonal prism are 5 inches, 8 inches, and 10 inches, respectively. Thus, the lateral Surface area or LSA $= Ph = (150) \times (55) = 8,250$ sq. The height of a pentagonal prism is 55 inches (given). The perimeter of a pentagonal prism is 150 inches (given). The perimeter of a pentagonal prism is 150 inches, and its height is 55 inches. $V = (5/2)$$\times a \times b \times h$ Solved Examples In other words, the volume of a regular pentagonal prism can also be calculated using the following formula. Thus, to calculate the area of the base of a regular prism, the following formula is applied:Īrea of base $= 1/2$$ \times$ perimeter $\times$ apothem length or $1/2$$ \times$$ 5bh$ However, to use the above formula, we need to know the area of the base of a pentagonal prism. So, we can obtain the value of the pentagonal prism using a simple formula. The volume of a pentagonal prism represents the space occupied by that prism. LSA $= 5bh$, where b is the side length of the base, and h is the height of the pentagonal prism The Volume of a Pentagonal Prism One can also calculate the lateral or curved surface area of a regular pentagonal prism using the formula below: Lateral Surface Area of a Pentagonal Prism Here a is the apothem length (a line that connects the center of the regular polygon to the midpoint of one of the sides of the polygon) of the pentagonal base, b is the side length of the base, and h is the height of a pentagonal prism. Thus, the total surface area of the regular pentagonal prism is calculated as: Total Surface Area of a Pentagonal PrismĪ regular pentagonal prism’s total surface area gives each face’s area (i.e., seven prism faces). Net of a Pentagonal Prism Surface Area of a Pentagonal PrismĪ pentagonal prism has two types of surface areas: total surface area and lateral surface area. Pentagon – US Defence Department Headquarter.You can find many real-life examples of pentagonal prisms. In this image, we can see that if we draw two pentagons (one on the top and the other on the bottom) and then connect them through straight lines, we will get a pentagonal prism. It is easier to understand how a usual pentagonal prism looks by going through the image below. Pentagonal Prism is a heptahedron that consists of: What is a Pentagonal Prism?Ī pentagonal prism or five-sided polygonal prism is a prism that consists of two pentagonal bases (the top and the bottom) and five rectangular sides.
