The diagonal of a cube is 8√3. find its volume and surface area.	Choose the correct choice from the following answers.
A) 354  B) 384  C) 324  D) 344  E) 364

Rationale: √ 3 . a = 8 √ 3 = > a = 8 volume = a ( power ) 3 = > ( 8 × 8 × 8 ) cm ( power ) 3 = > 512 cm ( power ) 3 surface area = > 6 a ( power ) 2 = > ( 6 × 8 × 8 ) cm ( power ) 2 = > 384 cm ( power ) 2 answer is b .
Answer: B
