A rectangular prism has six sides.
To understand why, let’s break it down: a rectangular prism, also known as a rectangular box or cuboid, consists of two identical rectangular bases and four rectangular lateral faces connecting the corresponding sides of the bases. This gives us a total of six rectangular faces. Each face of the prism is a rectangle, and when you consider that there are two bases and four lateral sides, you can easily tally the total. It’s important to visualize or even sketch a rectangular prism to see how these faces are arranged in three-dimensional space, which helps in understanding its structure.
