Question

If the total surface area of a Cube is
numerically equal to its volume. Find
it's lateral Surface area?​

Answer 1

Answer:-

Given,

TSA of Cube = Volume of Cube

We will write the formula of TSA and volume of the cube and will denote the side of the cube by x

Hence,

6x² = x³

Solving this we will get,

x = 6 units

Now, LSA of Cube = 4x²

= 4 * (6)²

= 4 * 36

= 144 sq units
