Area Of prism

Prism Definition

A Prism is a solid figure with a uniform cross section. Here are some of the examples of the Prisms:

Rectangular based prism

Area Of prism

Circular based prism (Cylinder)

Area Of prism

Triangular based prism

Area Of prism

Surface area of Prism

The surface area of a prism is always equal to the sum of the areas of all its faces, which includes the floor, walls, and roof. Because in a prism, the roof and the floor have same shape and their surface areas is always same which can be found out by

Surface area of Prism = 2 x area of the base+ perimeter of the base x Height

The actual formula to find out the circumference is used depending upon the shape of the base

Rectangular Prism

Area Of prism

Base Shape: Rectangle with length L and with width W

Area of the base: L*W

Perimeter: 2(L+W)

Surface area= 2LW+2(L+W)H

Circular based prism (Cylinder)

Area Of prism

Base Shape: Circle with radius of R

Area of the Base: PR^2

Perimeter of the base: 2PR

Surface area= 2PR^2 + 2PRH

Triangular based prism

Triangular based prism

Base Shape: Triangle with base B, height H and slides S1, S2 and S3

Area of the base: ½ B*H

Perimeter of the base: S1 + S2 +S3

Surface area = BH + (S1+S2+S3)H

Frequently Asked Questions

What is Prism?

The prism shape in maths can be defined as a solid figure with a uniform cross-section.

What is Meant by the Area of a Prism?

The area of a prism is defined as the total amount of space that the prism encloses in a three-dimensional space.

What is the Formula for Surface Area of a Prism?

The surface area of a prism is the summation of twice the area of the base and the product of perimeter of base and height. So,

Surface area of Prism = 2 x area of the base + perimeter of the base x Height

What is the Surface Area of a Rectangular Prism?

The surface area of a rectangular prism is:

A = 2(lb+lh+bh)
