Question

you must apply two coats of paint to the walls of the bathroom. the door and the window will not be painted. determine the total area to be painted (accurate to 5 decimals) and how many cans of paint will you need to purchase if one can covers 100 ft^2? you cannot purchase partial cans.

Answer 1

the walls are 8 ft high, the door measures 84 in. x 36 in., and the window measures 24 in. x 36 in.

Answer 2

so, the walls are 8' high. How wide are they? Are they all 4 the same width? If not, can we assume the room is rectangular?

At any rate, you surely know that for a rectangle, the area is height x width.

So, add up the areas for all the walls, then subtract the areas of the door and window.

Answer 3

But how long and wide are the walls??

What about the areas taken up by the counter and the tub?

Answer 4

5 ft by 7ft.

Answer 5

Boy, you're not willing to put anything into this, are you?

so, the painted area is (converting the door and window to feet, rather than inches):

4(5*7) + 7*3 + 2*3 = 167 ft^2

So, how many cans will it take, at 100 ft^2 per can?

Answer 6

Ignore that post. It added the window and door, rather than subtracting them. Also, you started out by saying the walls were 8' high. What's the 5x7 foot stuff?

And we <b><u>STILL</u></b> don't know how wide the walls are!!!!
