## EXAMPLE 1 Drawing a Net Draw a net of the triangular prism. SOLUTION – ppt video online download

Draw a net of the triangular prism to find the surface area to be painted. The surface area of a storage chest is 2250 square inches. Draw a net for each of the four faces of the chest, and use this to work out the dimensions of the storage chest.

## What is the net of a triangular prism?

A triangular prism’s net is made up of two triangles and three rectangles, with the triangles serving as the prism’s bases and the rectangles serving as the lateral faces. A rectangular prism’s net is made up of six rectangles, which serve as the shape’s bases and lateral faces.

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

The surface area of a right triangular prism is calculated using the formula (Length Perimeter) (2 Base Area) = (s1 s 1 s2 s 2 h)L bh, where b is the bottom edge of the base triangle, h is the height of the base triangle, L is the prism’s length, and s1 s 1, s2 s 2 are the base triangle’s two edges.

## How do you find the surface area of a net triangular prism?

Because they have two triangular faces opposite each other, triangular prisms have their own formula for calculating surface area: A=12bh. This formula is used to calculate the area of the top and bottom triangular faces, where A = area, b = base, and h = height.

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

The surface area of a prism is calculated by adding the sum of (twice the base area) and (the lateral surface area of the prism), which is given as S = (2 Base Area) (Base perimeter height), where “S” is the surface area of the prism.

## What is the area of prism?

## How do you find the base area of a rectangular prism?

It’s a rectangle with sides l and w in our notation, so its area is l * w, and the formula for the base area is A_b = l * w.

## What is the surface area of a triangular pyramid?

As a result, a triangular pyramid has a surface area of 140 square units.

## What is surface area formula?

Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape; we can also label the length (l), width (w), and height (h) of the prism and calculate the surface area using the formula SA=2lw 2lh 2hw.
