PLEASE HURRY!!
A typical juice box contains about 250 milliliters (ml.) of juice. It measures 10.5 cm by 6.5 cm by 4 cm.

a. What is the volume of this box in cubic centimeters?

b. Is this the best box size? Suppose the manufacturer wants to maximize profit by reducing packaging costs. What size rectangular box has the same volume as a typical juice box and uses the least cardboard?

c. Design a container (of any shape) that has the same volume as a typical juice box, using the least cardboard. (Be sure that it can be held comfortably by a child and can be assembled and stacked.) Explain your choice with enough information to convince a packaging engineer that it is the best shape
