Question

Which among the following is always greater for a cube?

• A. Lateral Surface Area
• B. Total Surface Area

Answer 1

The correct option is B Total Surface Area

Let the side of a cube be "s"
Total Surface Area is the area of all the $6$ sides of a cube , and

Lateral Surface Area is the area of all sides excluding the base and top, which means it takes into account only $4$ sides of the cube.

For example if we consider this cube:

Its Total Surface Area
$=6\times s^2=6\times 4\times 4=6\times 16=96c{m}^2$

And, Lateral Surface Area $=4\times s^2=4\times 4\times 4=64c{m}^2$

Therefore Total Surface Area $>$ Lateral Surface Area

This is true for cubes of any dimension.

Option (b.) is correct.
