13. Graded Exit Ticket The company that produces Sweet Crunch cereal wants to produce a family-sized box of its cereal. The regular sized box is a cube, and each side measures 8 in long. The company wants to double the length of the sides of the regular box to create the family-sized box of cereal. Should the company just double the price of the cereal? Why or why not.

14. Answer 8 in 16 in Volume 1 V = lwh V = (8)(8)(8) V = 512 cubic in V = lwh V = (16)(16)(16) V = 4096 cubic in Volume 2 The new box of cereal holds 8 times more cereal. Therefore, the company should more than double the price.
