Answer 1

Answer:

Hi !

Many a times it is very much advisable/beneficial to remember perfect squares/cubes of natural numbers.

The best example is this question!

It is given that the volume of the cube is 2744 cu cm.

Let the side of the cube be equal to ‘a’ cm; the volume of the cube would be => a^3

Or a^3 = 2744

Or a = 14 cm.

Now, the total surface area of the cube is 6(a^2)

= 6(14^2)

= 6 x 196

= 1176 sq cm.

Hope this helps! :)
