Surface Area Rectangular Prism Worksheet Answer Key Pdf
Introduction
Rectangular prisms are three-dimensional objects with six faces, and they are commonly used in geometry. The surface area of a rectangular prism is the sum of the areas of all six faces. This includes the top, bottom, front, back, left, and right faces. In this article, we will be discussing the surface area of rectangular prisms, and how to properly calculate it with our worksheet answer key pdf.
How to Find the Surface Area of a Rectangular Prism
To calculate the surface area of a rectangular prism, you need to know the length, width, and height of the object. The formula for calculating the surface area of a rectangular prism is:
Surface Area = 2lw + 2lh + 2wh
Where l is the length of the rectangular prism, w is the width, and h is the height. To use this formula, measure the length, width, and height of the rectangular prism. Multiply the length by the width and then multiply the result by 2. This gives you the area of the top and bottom faces of the prism. Next, multiply the length by the height and then multiply the result by 2. This gives you the area of the front and back faces of the prism. Finally, multiply the width by the height and then multiply the result by 2. This gives you the area of the left and right faces of the prism. Add all of these values together to find the surface area of the rectangular prism.
