This 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.
1. 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 10’3”, because that is incorrect. Convert the
measurements to all inches for step 2, and then convert back to square feet for
step 3.
2. Record your dimensions and, using the appropriate formula, find the surface
area of the room.
3. 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.
4. If a gallon of paint costs $22.95 plus 8% tax, what would be the total cost
to paint the room?
5. One inch is equivalent to 2.54 centimeters. Convert your English
measurements to metrics. Record each dimension in centimeters. Show your
conversions.
6. Find the volume in cubic centimeters. Be neat and precise.
7. If each dimension (length, width, and height) is doubled, what happens to
the volume of the room? Show your work.
8. Respond to at least two of your classmates’ postings. Review their
calculations and determine if their results seem reasonable for the size of the
room.Attachments
