Stat1: sufficient 600 = 6*a sqrt 2 --> a=10--> V=1000. Suff.
Stat2: draw a right triangle inside the cube. realize that legs of that rigth triangle are a sqrt2 and a. AS (probably meant to be denoted as AB?) equals a sqrt 3= 10 sqr 3 --> a=10, V = 1000. Suff

D for me .

1) cube SA = 6a^2 so a = 10
2) Diag = u find hypotenuse twice. so it can be found.
