Question 188520
An open box is made from a piece of cardboard 15 inches by 22 inches by cutting out squares from each corner. If the resulting bas has area of 110in(squared), what is the length of the sides of the squares? 
a) Draw and label a picture
b) Find the length of the squares 
------------------------
When the squares are cut out, the bottom will be (15-2x)*(22-2x) = 110
4x^2 - 74x + 330 = 110
4x^2 - 74x + 220 = 0
2x^2 - 37x + 110 = 0
x^2 - 18.5x + 55 = 0

The sides of the squares cut out = 3.72166... inches
