This math topic focuses on determining the number of blocks in a rectangular prism that have three outside faces. It is aimed at understanding the surface area concepts within the broader context of 3D shapes in an introductory geometry unit. Each question presents a different rectangular prism with dimensions specified, and students are asked to identify which multiple-choice option correctly represents the count of blocks with three visible sides. This requires visual and spatial reasoning to analyze 3D objects from different perspectives.
