The Total solution for NCERT class 6-12
The twofigures given are cylinder and cube.Both figures are alike in respect of their same height.Cylinder: d = 1 cm, h = 7 cmCube: Length of each side a = 7 cmBoth of the figures are different in respect of their shapes.Lateral surface of cylinder = 2ฯrh= 2 ร 22 ร 7 ร7 = 154 cm2Lateral surface of the cube = 4l2 =4 ร (7)2 =4 ร 49 = 196So, cube has the larger lateral surface = 196 cm2.
