![]() ![]() ![]() As the base of an equilateral prism is similar to the shape of an equilateral triangle so we used the formula of area of equilateral triangle. Also, we need to be careful while applying the formula, as wrong formula will give us the wrong result. A linear equation of the form \ has only one solution. Step 2: The length of the prism is 15 in. So its area is found using the formula, 3a 2 /4 3 (6) 2 /4 93 square inches. A linear equation in one variable is an equation which has only one variable with highest exponent 1 and is of the form \, where \ and \ are integers. Step 1: The base triangle is an equilateral triangle with its side as a 6. We have formed a linear equation in one variable using the given information in this question. Since the volume of an equilateral triangular prism is 3 4 a2h 3 4 a 2 h ,where a a is the side length of the base triangle and h h is the height of the prism. We will use the formula of the area of an equilateral triangle is given by the formula \ dm. Then, we will solve the equation to get the value of \, and hence, find the length of the side of the base. We will use the formula for the area of an equilateral triangle in the formula for the volume of the prism, and obtain an equation in terms of \. We will assume \ to be the length of the side of the base of the right equilateral prism. ![]() Volume of a pentagonal prism = (0.3) (5) (0.Here, we need to find the length of the side of the base of the prism. NOTE: This formula is only applied where the base or the cross-section of a prism is a regular polygon.įind the volume of a pentagonal prism with a height of 0.3 m and a side length of 0.1 m. S = side length of the extruded regular polygon. The volume of a hexagonal prism is given by:Ĭalculate the volume of a hexagonal prism with the apothem as 5 m, base length as 12 m, and height as 6 m.Īlternatively, if the apothem of a prism is not known, then the volume of any prism is calculated as follows Therefore, the apothem of the prism is 10.4 cmįor a pentagonal prism, the volume is given by the formula:įind the volume of a pentagonal prism whose apothem is 10 cm, the base length is 20 cm and height, is 16 cm.Ī hexagonal prism has a hexagon as the base or cross-section. The apothem of a triangle is the height of a triangle.įind the volume of a triangular prism whose apothem is 12 cm, the base length is 16 cm and height, is 25 cm.įind the volume of a prism whose height is 10 cm, and the cross-section is an equilateral triangle of side length 12 cm.įind the apothem of the triangular prism. The polygon’s apothem is the line connecting the polygon center to the midpoint of one of the polygon’s sides. The formula for the volume of a triangular prism is given as Volume of a triangular prismĪ triangular prism is a prism whose cross-section is a triangle. Let’s discuss the volume of different types of prisms. Where Base is the shape of a polygon that is extruded to form a prism. The volume of a Prism = Base Area × Length The general formula for the volume of a prism is given as Since we already know the formula for calculating the area of polygons, finding the volume of a prism is as easy as pie. The formula for calculating the volume of a prism depends on the cross-section or base of a prism. The volume of a prism is also measured in cubic units, i.e., cubic meters, cubic centimeters, etc. The volume of a prism is calculated by multiplying the base area and the height. To find the volume of a prism, you require the area and the height of a prism. pentagonal prism, hexagonal prism, trapezoidal prism etc. Other examples of prisms include rectangular prism. In this question, we are given the density but not the volume, so let’s begin by calculating the volume of the triangular prism. This time, we are asked to work out the mass, so well need the formula for mass (Mass Density Volume). For example, a prism with a triangular cross-section is known as a triangular prism. Work out the mass of this triangular prism if the density is 3 g/cm³. Prisms are named after the shapes of their cross-section. The area of the base l denotes the length of the side of equilateral triangle and the angle included is of. By definition, a prism is a geometric solid figure with two identical ends, flat faces, and the same cross-section all along its length. ![]() In this article, you will learn how to find a prism volume by using the volume of a prism formula.īefore we get started, let’s first discuss what a prism is. The volume of a prism is the total space occupied by a prism. Volume of Prisms – Explanation & Examples ![]()
