Describe how the two figures at the right are alike and how they are different. Which box has larger lateral surface area?

The figure is shown:

Similarity: Their dimensions are equal, i.e. 7 cm width, breadth and height


Difference: The figure on the left is cylindrical and that on the right is cuboidal.


So, surface area of cylinder = 2 π rh = 2 × × 7


= 154 sq. cm


And surface area of the cube = 4 × side2


= 4 × 72


= 196 sq. cm


Clearly, the cube has a larger surface area than the cylinder.
