The sum of the areas of the faces of a cube is 300 square inches. The volume of this cube, in cubic inches, is

(A) 125√2

(B) 250√2

(C) 300√2

(D) 2,500

(E) 125,000

Since there are 6 faces of a cube, if we let the side of the cube = n, we have:

6n^2 = 300

n^2 = 50

n = √50

Since the volume of the cube is n^3, we have:

volume = √50 x √50 x √50 = 50√50 = 50 x √25 x √2 = 50 x 5 x √2 = 250√2

Answer: B
