surface area = 6a^2
6a^2 = 150
a^2=25
a=5

side=5

v=a^3 = 125

The properties of all SOlids needed for GMAT as attached

The Surface Area of the cube = 6*Side^2 = 150

i.e. SIde^2 = 25

i.e. Side = 5

Volume = Side^3 = 5^3 = 125

$$6a^2 = 150$$

So, $$a = 5$$

Thus, volume will be $$5^3 = 125$$, Answer will be (D)
