the whole room/ all four walls

aripotta · Answer

ok...i don't understand "45' x 150' and 10 feet high"

aripotta · Answer

a wall is 2d so we don't need three dimensions...

aripotta · Answer

if the wall is 45 ft by 150 ft, then that, i can understand

anonymous · Answer

its a large room you do need to know how high, so you need three dimenions. the surface area is 3900 ft.

anonymous · Answer

awesome

anonymous · Answer

the floor is 45 by 150. this shows that it is not a perfect square room. so the 10 feet does factor into this. one set of walls will be 45 by 10 feet. (note to convert the feet) and the other set will be 150 by 10 feet. so basically 2(45 inches x 10 ft) + 2(150in x 10 ft)

aripotta · Answer

so they're painting the floor too?

anonymous · Answer

they are no painting the floor. we figured out it takes 9.75 gallons to paint the four walls.
