Question

Volume of cube is 343cm sqare then find it surface area?

Answer 1

Answer:  Hence the surface area of cube : $294 \ square \ cm$  

Step-by-step explanation:

Alright, let get started.

Volume of cube is given by : $343 \ cubic \ cm$

The formula of volume of cube is given as : $a^3$

$a^3=343$

So, taking cubic root on both sides

$a = 7$

It means, the side of the cubs is 7 cm.

The formula of surface area of cube is : $6a^2$

hence the surface area of cube : $6 \times 7^2$

Hence the surface area of cube : $294 \ square \ cm$   :  Answer
