If you stack rectangles, the resulting 3-D shape will be a rectangular prism, also known as a cuboid. This shape has six rectangular faces, with opposite faces being congruent. The dimensions of the prism depend on the size and number of rectangles stacked. If the rectangles are arranged in a specific way, they can also form other shapes, but the most common outcome is a rectangular prism.

Oh, what a delightful question! If you stack rectangles on top of each other, you'll create a wonderful 3D shape called a rectangular prism. Just imagine those rectangles piling up so neatly and forming a solid shape with six faces, where each face is a rectangle. Keep on creating, my friend!
