Wedding rings are packed into little boxes which all measure 3cm by 3cm by 0.5cm. If 48000 of these boxes are packed in a cubic box with so space wasted, how long is the edge of the box?
-
Vol of each box = 9/2 c.c.
Vol of 48000 boxes = 216000 c.c. = x^3 where x is th edge of the bigger box
Clearly x = 60 cm
Vol of 48000 boxes = 216000 c.c. = x^3 where x is th edge of the bigger box
Clearly x = 60 cm

144,000cm (3*48,000) or 24,000cm (.5*48,000)
