a painter is painting the ceiling of a square room. The walls are all 15 ft long. If a gallon of paint covers 45 square feet, how many gallons of paint will be needed to cover the entire ceiling?
A. 4 Gallons
B. 5 Gallons
C. 6 Gallons
D. 3 Gallons
Who makes up these questions or what kind of strange paint is this?
To paint a ceiling of that size should take about 1/2 gallon
( I know, I have too much time on my hand)
The room is 15x15 feet, making 225 sq ft.
Each gallon covers 45 sq ft
5*45 = 225, so it will take 5 gallons.
Or, as we solved it, 225/45 = 5
15 * 15 = 225 square feet
225 / 45 = ?
15*15/45 = 5
how did you get 5
What do YOU get when you divide 225 by 45?
225/45 = ?
you get 5
i know that but i did not understand
but now i do
