All squares are rectangles. Some rectangles are not cubes. What can be inferred?

All squares are rectangles. Some rectangles are not cubes. What can be inferred?

Step 1: Understand that all squares are a type of rectangle. This means every square can be classified as a rectangle.
Step 2: Recognize that some rectangles do not have the properties of a cube. A cube is a three-dimensional shape, while rectangles are two-dimensional.
Step 3: Since all squares are rectangles, if some rectangles are not cubes, it follows that those rectangles could include squares.
Step 4: Therefore, it can be concluded that some squares (which are rectangles) are also not cubes.
