Surface Area Of A Prism Formula

Surface Area Of A Prism Formula

In Mathematics, a prism is an important member of the polyhedron family, defined as a three-dimensional shape made up of two identical polygons facing each other and laterally connected by rectangular or parallelogram faces. Identical polygons, which are triangles, squares, rectangles, pentagons, or other n-sided polygons, are called the bases of prisms, and other faces of the prism are parallelograms or rectangles. There are two types of prisms based on polygon-based types: regular prisms and irregular prisms. There are two types of prisms, rectangular prisms and oblique prisms, depending on the orientation of the base. Also, there are different types of prisms based on the shape of the base of the prism. 

• triangular prism,
• prism,
• right angle prism,
• pentagonal prism,
• hexagonal column,
• Octagonal prism etc.

The Surface Area Of A Prism Formula of a three-dimensional solid prism depends on the shape of its base. The Surface Area Of A Prism Formula is the total area occupied by the faces of the prism, and the prism is a polyhedron with flat faces. The surface of a three-dimensional solid prism is determined by the shape of its base. The Surface Area Of A Prism Formula is the total area occupied by the faces of the prism. A prism is a flat polyhedron. No rounds. In this article, we will discuss different types of prismatic surfaces and various problems based on them. 

What is the surface of a prism? The total amount of space occupied by the flat faces of a prism is called the Surface Area Of A Prism Formula. Calculating the total space occupied by all faces of that particular type of prism, or the sum of the areas of all faces (or surfaces) on the 3D plane, gives the Surface Area Of A Prism Formula. Prism Formula – Derived and Solved Examples A prism is a polyhedron with two congruent parallel bases laterally connected by parallelogram or rectangular (for right-angled prisms) faces. The number of faces is the same as the number of sides of the base polygon. For a base polygon of nnn sides, the prism has nnn rectangular faces. Therefore, the total number of faces of a prism with n-sided bases is n+2n+2n+2. Students can check all the formulas in the Surface Area Of A Prism Formula on Extramarks.

What Is The Surface Area Of Prism?

The Surface Area Of A Prism Formula refers to the total area occupied by the flat faces of the prism. Finding the Surface Area Of A Prism Formula means calculating the total space occupied by all faces of that particular type of prism, or the sum of the areas of the faces or surfaces present in a 3D plane.

Surface Area Of A Prism Formula

To find the prism surface, use the general formula: The total area of a prism is the sum of the areas of its sides and its two flat bases. Let’s look at the surface of the prism formula: 

The lateral area is the area of the vertical plane when the prism faces its base up and down. Side area of a prism = base x height.

Total prism area = prism face area + base area = (2 × base area) + face area or (2 × base area) + (base perimeter × height).

There can be many types of prisms. Different types of prisms have different bases, as do the formulas for determining the Surface Area Of A Prism Formula.

A given prism has two triangular bases. So, according to the base area of ​​the prism formula, (2 × base area) + (base circumference × height). Here the base is a triangle, so the base A = ½ bh and the base perimeter = the sum of the three sides of the triangle, or (a + b + c). Substituting the appropriate values ​​into the formula gives the surface area of ​​the triangular prism = bh + (a + b + c)H = .(2A + PH).

How To Calculate The Surface Area Of Prism?

Here are the steps to determine the Surface Area Of A Prism Formula.

 Step 1: Write down the given dimensions of the prism. Step 2: Substitute the surface dimensions in the prism formula (2 × base area) + (base perimeter × height). Step 3: Find the value of the surface area of the prism, and finally put the units of the surface area of ​​the prism (square units). Example: Find the surface of the above prism with a base area of ​​12 square units, a base perimeter of 18 units, and a prism height of 6 units.

Solution: As students know, the surface of the prism is given by

Surface area of ​​prism = (2 x base area) + (bottom circumference x height)

Floor area = 12 square units

Base scope = 18 units

Prism height = 6 units

So the Surface Area Of A Prism Formula= (2 × 12) + (18 × 6)

⇒ S = 132 units2

∴ The Surface Area Of A Prism Formula is 132 square units.

Solved Examples

Example 1: If the base and height of a triangular prism are 8 and 14 units, respectively, and the base of an equilateral triangle is 9 units tall, what is the surface area of ​​the triangular prism?

Solution: The information given is base = 8 units, height of base = 9 units, length of each side of the base = 8 units, height of prism = 14 units. 

Area of ​​triangular prism = (bh + (a + b + c)H)

Students must know that all three sides of an equilateral triangle are equal. So a = b = c = 8 units

Area = (8 × 9) + (8 + 8 + 8) × 14

Area = 72 + 24 x 14

Area = 72 + 336

Area = 408 units 2

So the surface area of ​​a given triangular prism is 408 units2

Example 2: Find the side area of ​​a prism with a base perimeter of 200 inches and a prism height of 75 inches. If the base area is 250 square inches, also find the Surface Area Of A Prism Formula. 

Solution: The base of a prism is a polygon. Therefore, the surface area of ​​the sides of the prism is L = perimeter of the base × height of the prism.

Side area = 200 x 75 = 15,000 square inches

S = (2 × base area) + (base perimeter × height) where “S” is the Surface Area Of A Prism Formula. Footprint = 250 square inches

S = (2 × 250) + (15000)

S = 500 + 15000 = 15500 square inches

So a given prism has a side surface area of ​​15,000 in2 and a prism has a Surface Area Of A Prism Formula of ​​15,500 in2.
