The largest possible cone that can fit inside a cube will have its base diameter equal to the side of the cube and its height equal to the side of the cube.
Given the cube has an edge of 25cm, the diameter of the cone's base is 25 cm therefore, the radius of the cone's base is half of the diameter.
