This math topic focuses on identifying and classifying complex 3D shapes as part of an introductory unit on shape classification in geometry. The practice problems require recognizing and naming various 3D shapes including cones, spheres, cubes, prisms (triangular, hexagonal, rectangular, and pentagonal), pyramids (square, rectangular, hexagonal, and pentagonal), cylinders, tetrahedrons, and more. Each question presents a different scenario with multiple shapes to identify, enhancing the ability to differentiate between complex geometric forms.
