Project: Sweat Equity
Objective: The cost of purchasing the material for home projects will
be determined.
Use the floor plan on the previous page for this project. Show all formulas used and the work to
support your results. Keep your work neat and organized. Work that needs deciphering will not be
graded.
Note: A fraction of a tile, gallon of paint, etc. cannot be purchased. Another tile, gallon of paint, etc.
must be purchased to cover this fraction. Thus, the answer to perimeter, area, and volume problems
will be bumped up to the next whole number. If a shape has to be partitioned, the intermediate
perimeters and areas will be rounded to tenths.
