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?
What is the surface area of the container?
Unless the problem states what the container shape is, you don't know.
could u help me set it up? like with the formula and everything? it's just a little confusing.
plzzzz help!! thx.
anyone...? i need sleeppppp. plz tell me now if no one understands so i can go to bed and get in trouble for not finishing my homework tomorrow.
ANYYBODDYY plz it would be nice to know if someone had the knowledge to help me
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.
To find out how much the paint costs, we need to calculate the total area that needs to be covered and then determine the total cost based on the rate per jar. Here's the step-by-step process:
1. Calculate the total area to be covered by the paint. We are given that each jar of paint covers 800cm² and the container has two layers. Therefore, the total area to be covered is 800cm² x 2 = 1600cm².
2. Determine the cost of one jar of paint. We are given that one jar of paint costs $6.05.
3. Calculate the total cost of the paint by multiplying the cost per jar by the number of jars required. Since we know that one jar covers 1600cm² and we need to cover a total area of 1600cm², we divide the total area by the area covered per jar: 1600cm² ÷ 800cm²/jar = 2 jars.
4. Multiply the cost per jar ($6.05) by the number of jars (2) to find the total cost of the paint: $6.05/jar x 2 jars = $12.10.
Therefore, the paint costs $12.10.
So u use the formula for S.A which is 2*pi*r*h, but how do u know what shape the container is?
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
