Rectangular Prisms
A rectangular prism is a three-dimensional shape with six faces, where each pair of opposite faces is identical in size and shape. The faces are all rectangles, and the edges where the faces meet are all right angles.Formulas for Rectangular Prisms
1. Surface Area: The surface area of a rectangular prism is the total area of all its faces. The formula for the surface area (SA) of a rectangular prism is:SA = 2lw + 2lh + 2wh
where l is the length, w is the width, and h is the height of the prism.2. Volume: The volume of a rectangular prism is the amount of space it encloses. The formula for the volume (V) of a rectangular prism is:
V = lwh
where l is the length, w is the width, and h is the height of the prism.
Study Guide
To understand rectangular prisms better, make sure to focus on the following key points:- Understanding the concept of a rectangular prism and being able to identify its features, such as faces, edges, and vertices. - Knowing the formulas for calculating the surface area and volume of a rectangular prism, and being able to apply these formulas to solve problems. - Practicing different types of problems involving rectangular prisms, such as finding the dimensions given the volume or surface area, or finding the surface area given the dimensions.Practice Problems
