Question

The surface area of a cube whose volume is $343c{m}^3$ is $Kc{m}^2$, the value of K is

• A. 180
• B. 364
• C. 294
• D. 394

Answer 1

The correct option is C 294

The volume of a cube $=343c{m}^3$

$a^3=343$

$a=7cm$

The surface area of the cube $=Kc{m}^2$

$6a^2=K$

$6\times 7^2=k$

$k=294$

Hence, this is the answer.
