Question

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

• A. 180
• B. 364
• C. 294
• D. 394

Answer 1

Answer: (C)

294

The volume of cube is 343 $m^3$ . let side of cube a m

$\therefore a^3=343\Rightarrow a=7m$

Then surface area K =$6a^2=6\times (7{)}^2=294m^2$
