1.3 Step 1: Identify the components of a square-based pyramid. A square-based pyramid has one square base. Step 2: Count the faces. It has 4 triangular faces that rise from the sides of the square base and meet at a single apex. Adding the base, the total number of faces is 1 (base) + 4 (triangular sides) = 5 faces. Step 3: Compare with the given options. The calculated number of faces is 5, which matches option D. The student's answer is ✅ Correct. The correct option is D. Five. 1.4 Step 1: Observe the image of the marking pen against the ruler. The ruler starts at 0 cm. The left end of the marking pen aligns with the 0 cm mark on the ruler. Step 2: Read the measurement at the other end of the pen. The right end of the marking pen aligns with the 10 cm mark on the ruler. Step 3: Determine the length. The length of the pen is the difference between the end mark and the start mark: 10 cm - 0 cm = 10 cm. Step 4: Compare with the given options. The calculated length is 10 cm, which matches option B. The correct option is B. 10 cm. That's 2 down. 3 left today — send the next one.
