Write a C++ program to figure out how many boxes of flooring materials are needed The user will enter the length and width (in feet) of the floor along with what percent extra (overage) to order You always want a little more material than you think.

For example, if you install tile on an angle, you waste more than if they are not on an angle. Output the number of boxes (rounded to a whole number) and the cost Each box of materials cost $21.95 and contains 40 square feet of material For example, if the dimensions are 10.5 and 12.0 feet with a 15% overage The area of the floor is 126.0 square feet 15% overage is another 18.9 square feet That is a total of 144.9 square feet which is 3.6225 boxes 3.6225 rounded is 4 boxes (because 3.6225 is closer to 4 than 3) 4 boxes will cost $87.8 this is what ai have done so far but is not giving me the right numbers:
