you want to paint the walls of your bedroom. Two walls measure 19 ft by 9 ft, and the other two walls measure 14 ft by 9 ft. The paint you wish to purchase costs $17 per gallon, and each gallon will cover 400 ft2 of wall. Find the total amount you will spend on paint.
To find the total amount you will spend on paint, follow these steps:
Step 1: Calculate the area of each wall.
Wall 1: 19 ft x 9 ft = 171 ft²
Wall 2: 19 ft x 9 ft = 171 ft²
Wall 3: 14 ft x 9 ft = 126 ft²
Wall 4: 14 ft x 9 ft = 126 ft²
Step 2: Calculate the total area of all four walls.
Total Area = Area of Wall 1 + Area of Wall 2 + Area of Wall 3 + Area of Wall 4
Total Area = 171 ft² + 171 ft² + 126 ft² + 126 ft²
Total Area = 594 ft²
Step 3: Calculate the number of gallons needed.
Number of Gallons = Total Area / Coverage per Gallon
Number of Gallons = 594 ft² / 400 ft²/gallon (approx.)
Number of Gallons = 1.485 gallons
Step 4: Round up the number of gallons to the nearest whole number.
Number of Gallons = 2 gallons (rounded up)
Step 5: Calculate the total cost of paint.
Total Cost = Number of Gallons × Cost per Gallon
Total Cost = 2 gallons × $17/gallon
Total Cost = $34
Therefore, you will spend a total of $34 on paint.
To find the total amount you will spend on paint, you need to calculate the total area of the walls and then determine how many gallons of paint you will need.
Let's calculate the area of each wall first:
Wall 1: 19 ft x 9 ft = 171 ft²
Wall 2: 19 ft x 9 ft = 171 ft²
Wall 3: 14 ft x 9 ft = 126 ft²
Wall 4: 14 ft x 9 ft = 126 ft²
Now, let's calculate the total area of all four walls:
Total area = Wall 1 + Wall 2 + Wall 3 + Wall 4
Total area = 171 ft² + 171 ft² + 126 ft² + 126 ft²
Total area = 594 ft²
Next, to determine how many gallons of paint you will need, divide the total area by the coverage of one gallon of paint:
Gallons of paint needed = Total area / Coverage of one gallon of paint
Gallons of paint needed = 594 ft² / 400 ft²/gallon
Gallons of paint needed = 1.485 gallons
Since you cannot purchase a fraction of a gallon, you would need to round up to the next whole gallon. Therefore, you will need 2 gallons of paint.
Finally, to find the total amount you will spend on paint, multiply the number of gallons needed by the price per gallon:
Total cost = Number of gallons needed x Price per gallon
Total cost = 2 gallons x $17/gallon
Total cost = $34
So, you will spend a total of $34 on paint for your bedroom walls.
13
total area = (19)(9) + 14(9) ft^2
= 297 ft^2
number of cans needed = 297/400 = .7425
Assuming you are buying the paint only by the gallon, you will have to buy 1 gallon, so the cost will be $17.00
btw, time to update that textbook, paint at $17 a gallon ????
