Here are the solutions to the questions: 2. Count the number of surfaces (faces) in the given solid. Step 1: Identify all the distinct flat surfaces of the 3D object. Step 2: Count the horizontal surfaces: • The top surface of the upper block. (1 face) • The exposed top surface of the lower block (the "step" surface). (1 face) • The bottom surface of the entire solid. (1 face) Total horizontal faces = 3. Step 3: Count the vertical surfaces: • The front surface of the upper block. (1 face) • The front surface of the lower block (the part below the upper block
