# How To Find The Lateral Area Of A Triangular Prism?

## How do you find the lateral area of a right triangular prism?

To find the surface area of a triangular prism, use the formula Surface Area = L + 2B, where L is the lateral area and B is the area of the base.

Find the lateral area by calculating the perimeter of the base and multiply it by the height of the prism.

## How do you find the lateral area of a prism?

When a prism has its bases facing up and down, the lateral area is the area of the vertical faces. (For a rectangular prism, any pair of opposite faces can be bases.) The lateral area of a right prism can be calculated by multiplying the perimeter of the base by the height of the prism.

## How do you find the lateral area of a triangular pyramid?

Lateral and Total Surface Area- Triangular Pyramid –

## What is the lateral face of a triangular prism?

The two-dimensional shapes that form a three-dimensional shape are called faces. The top and bottom, which are triangles, are bases. The three rectangles are called lateral faces. A triangular prism has five faces consisting of two triangular bases and three rectangular lateral faces, and a base is also a face.

## What is the formula for surface area?

We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

## How do you work out the total surface area of a triangular prism?

Surface area of a triangular prism –

## What is the formula for finding the area of a prism?

The general formula for the total surface area of a right prism is T. S. A. =ph+2B where p represents the perimeter of the base, h the height of the prism and B the area of the base.

## How do you work out the area of a prism?

To find the surface area of a prism (or any other geometric solid) we open the solid like a carton box and flatten it out to find all included geometric forms. To find the volume of a prism (it doesn’t matter if it is rectangular or triangular) we multiply the area of the base, called the base area B, by the height h.

## How do you find the total surface area of a pyramid?

To find the surface area of a pyramid, start by multiplying the perimeter of the pyramid by its slant height. Then, divide that number by 2. Finally, add the number you get to the area of the pyramid’s base to find the surface area. To learn how to find the surface area of a square pyramid, scroll down!

## How do you find the total surface area of a sphere?

To find the surface area of a sphere, use the equation 4πr2, where r stands for the radius, which you will multiply by itself to square it. Then, multiply the squared radius by 4. For example, if the radius is 5, it would be 25 times 4, which equals 100.

## How fo you find the volume of a pyramid?

To calculate the volume of a pyramid with a rectangular base, find the length and width of the base, then multiple those numbers together to determine the area of the base. Next, multiply the area of the base by the height of the pyramid. Take that result and divide it by 3 to calculate the pyramid’s volume!
