his Discussion tests your ability to use a ruler and convert from Standard English measure to Metrics. You will then apply your knowledge of the geometric measurements of area and volume through real world problems.
- Choose a room in your house. Measure the length, the width, and the height. Make sure you use feet and inches. Most rooms are not a whole number, such as 10 feet; they are 10 feet and 3 inches, or 9 feet 6 inches, etc.
NOTE: Do not use decimal numbers for the feet. For example, do not write 10.3 to mean 10â€™3â€, because that is incorrect. Convert the measurements to all inches for step 2, and then convert back to square feet for step 3.
- Record your dimensions and, using the appropriate formula, find the surface area of the room.
- A gallon of paint covers about 350 square feet. How many gallons would be required to paint the room? Round up to the nearest gallon.
- If a gallon of paint costs $22.95 plus 8% tax, what would be the total cost to paint the room?
- One inch is equivalent to 2.54 centimeters. Convert your English measurements to metrics. Record each dimension in centimeters. Show your conversions.
- Find the volume in cubic centimeters. Be neat and precise.
- If each dimension (length, width, and height) is doubled, what happens to the volume of the room? Show your work.
