(a)
To write: A polynomial function that models the volume of the new box.
(a)
Answer to Problem 11CFU
Explanation of Solution
Given information: Manufacturing: The It’s A Snap Puzzle Company is designing new boxes for their 2000 piece 3-D puzzles. The old box measured 25 centimeters by 30 centimeters by 5 centimeters. For the new box, the designer wants to increase each dimension by a uniform amount.
Calculation:
Increasing each dimension by a uniform amount gives:
(b)
To write: An equation that models the situation in which the volume of the new box must be 1.5 times the volume of the old box to hold the increase in puzzle pieces.
(b)
