POW #10

Grace wanted to build a house for her cat Samantha.  She picked out the bottom of a box at Sobey's 45 cm x 35 cm x 20 cm.  She thought that the outside of the box looked quite boring, so she wanted to paint it the same hot pink colour that she saw in Mr. Vigna's office.  What is the total surface area of the box that Grace has to paint?  Note:    Grace does not want to paint the inside of the box.

Due:  Friday, March 23rd
