Question

Find the surface area of a cube whose volume is 343m cube.

Answer 1

The answer is 294m2 and the length of one side is 7m

Answer 2

Hey !!

Let us consider the side of the cube be 'a'

So, therefore

                      Volume = (a)³ = 343            (GIVEN)          

a = ∛343 = 7 cm

Now, T.S.A (Total Surface Area) be = 6a²

         = 6 ( 7 )²            

         = 6 ( 49 )          

         = 249 cm²        ( FINAL RESULT )

Good luck !!
