Let:
     Width:  W
     Length:  2W - 5  (5 meters less than twice the width)
     Height:  3W + 4  (4 meters more than 3 times the width)

Volume of rectangular box:
    (w) (L) (H) = 520

Substitute:
    (W) (2W-5) (3x + 4) = 520

ANSWER:  D
     
1 5 1
Typo error, should be: (W)(2W-5)(3W + 4) = 520, and not (3x + 4).
