- The following problem is from both the 2007 AMC 12B #1 and 2007 AMC 10B #1, so both problems redirect to this page.
Problem
Isabella's house has bedrooms. Each bedroom is
feet long,
feet wide, and
feet high. Isabella must paint the walls of all the bedrooms. Doorways and windows, which will not be painted, occupy
square feet in each bedroom. How many square feet of walls must be painted?
Solution
There are four walls in each bedroom (she can't paint floors or ceilings). Therefore, we calculate the number of square feet of walls there is in one bedroom:
We have three bedrooms, so she must paint
\[292\cdot3=\boxed{\textbf(E) }876}\] (Error compiling LaTeX. Unknown error_msg)
square feet of walls.
