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

A triangular prism has three rectangular sides and two triangular faces.

To find the area of the rectangular sides, use the formula A = lw, where A = area, l = length, and h = height.

To find the area of the triangular faces, use the formula A = 1/2bh, where A = area, b = base, and h = height.

## How do you calculate the surface 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 surface area of a triangular prism Wikihow?

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 missing height of a triangular prism?

Finding the missing length on a triangular prism when given the

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

Surface area of a triangular prism –

## How do u find the 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.

## What is the formula of a prism?

The formula for the volume of a prism is V=Bh , where B is the base area and h is the height. The base of the prism is a rectangle. The length of the rectangle is 9 cm and the width is 7 cm.

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

Surface area of a triangular prism –

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

The formula to find the surface area of a rectangular prism is A = 2wl + 2lh + 2hw, where w is the width, the l is the length, and the h is the height.

## How do I find the base of a triangle?

Find the Base of a Triangle Given Area / Literal Equation –

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

To find the surface area of a cylinder add the surface area of each end plus the surface area of the side. Each end is a circle so the surface area of each end is π * r2, where r is the radius of the end. There are two ends so their combinded surface area is 2 π * r2.

## What is the surface area of a parallelogram?

Opposite sides are equal in length and opposite angles are equal in measure. To find the area of a parallelogram, multiply the base by the height. The formula is: A = B * H where B is the base, H is the height, and * means multiply.
