Question

A cube has numerically equal surface area and volume find the edge of such cube

Answer 1

Hi Friend!!!!

Let 'a' be the edge of the cube ,

It is given that ,

S A of the cube = Volume of the cube

Therefore ,

6a² = a³

a³/a² = 6

a = 6 units ...

Hope it helps

Answer 2

Total surface area of cube =6×a^2
Volume of cube =a^3
Since both are numerically equal,so
Total surface area of cube=Volume of cube 6×a^2 =a^3
6=a^3 /a^2
6=a^3 - 2
6=a^1
Therefore edge of the cube =6unit
