Let the edge of the cube be 'a' cm. Then, total surface area of the cube = 6a2 So, 6a2 = 216 a = 6 Therefore, radius of the cone = 6 X 2 = 12 cm So, slant height of the cone = √(radius) 2 + (height) 2 = √(162 + 122) = √400 = 20 cm So, curved surface area of the cone = π X radius X slant height = 3 X 12 X 20 = 720 cm2
