# 12 2 Surface Areas Of Prisms And Cylinders Worksheet Answers

## What are Prisms and Cylinders?

Prisms and cylinders are two types of 3D objects that share some similarities and differences. A prism is a solid three-dimensional shape with flat faces that are all the same shape. A cylinder is a solid three-dimensional shape with two circular faces. Both objects have flat faces and straight edges, but prisms have more than two faces, while cylinders have only two.

## What is the surface area of a prism or a cylinder?

The surface area of a prism or a cylinder is the total area of all its faces combined. In other words, it is the sum of the areas of each face. The surface area of a prism or a cylinder can be calculated by adding the areas of its faces or by using the formula SA= 2πrh + 2πr2, where r is the radius of the cylinder and h is the height.

## How to Calculate the Surface Area of Prisms and Cylinders?

Calculating the surface area of prisms and cylinders is quite easy. First, you need to find the area of each face. To find the area of a face, you will need to measure the length and width of the face and then multiply them together. Once you have the areas of all the faces, simply add them together to get the surface area of the prism or cylinder.

## 12 2 Surface Areas Of Prisms And Cylinders Worksheet Answers

To help you understand how to calculate the surface area of prisms and cylinders, here are the answers to the 12-2 Surface Area of Prisms and Cylinders worksheet. The surface area of a rectangular prism is calculated by adding the area of its six faces. To find the area of each face, multiply the length and width of the face. The surface area of a cylinder is calculated by using the formula SA= 2πrh + 2πr2, where r is the radius of the cylinder and h is the height.

### Conclusion

Calculating the surface area of a prism or a cylinder is quite straightforward. You simply need to measure the length and width of the faces and then add their areas together. You can also use the formula SA= 2πrh + 2πr2 to calculate the surface area of a cylinder. With the help of the answers to the 12-2 Surface Area of Prisms and Cylinders worksheet, you can easily calculate the surface area of a prism or a cylinder.
