Answer: The cone has a larger volume.
Step-by-step explanation:
Volume of a cone = ⅓πr²h
where, radius = 5cm
height = 10cm
Volume = ⅓ × 3.142 × 5² × 10
Volume of cone = 261.83cm³
Volume of square pyramid = A(h/3)
where, A = 10 × 10 = 100cm²
Volume = 100 × (5/3)
Volume of square pyramid = 166.67cm³
Therefore, the cone has a larger volume.
