The container is coated with 2 layers of specialty paint that costs $6.05 per jar. Each jar pf paint covers 800cm2. How much does the paint cost?

math 
Ms. Sue,
What is the surface area of the container?

math 
drwls,
You need to know the "container" area that you are covering. Divide that by 800 cm^2 for the number of jars per coating layer. Double that for two coats. Then take the next larger integer if there is a fraction left over.
Then multiply that integer number of jars by $6.05

beeca,
So u use the formula for S.A which is 2*pi*r*h, but how do u know what shape the container is?

math 
drwls,
Unless the problem states what the container shape is, you don't know.

drwls,
Your problem cannot be solved without the area. I have no idea what kind of container you are talking about. Somewhere along the line, you have not communicated all the information needed.
