Choose a room in your house. Measure the length, 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 3 inches, or 9 feet 6 inches, etc. Record the dimensions and using the appropiate 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 to 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. Show your conversions. Find the volume in cubic centimeters. If each dimension (length, width and height is doubled, what happens to the volume of the room? Show your work.
