To calculate the total area of the house that needs to be painted, we need to find the sum of the areas of the four walls and the roof.
The area of each wall can be calculated using the formula: length * height.
So, the total area of the four walls is: 2 * (length * height) + 2 * (width * height)
= 2 * (69 ft * 68 ft) + 2 * (55 ft * 68 ft)
= 2 * 4692 ft² + 2 * 3740 ft²
= 9376 ft² + 7480 ft²
= 16,856 ft²
The area of the roof can be calculated using the formula: length * width.
So, the area of the roof is: 69 ft * 55 ft = 3,795 ft².
The total area of the house that needs to be painted is: 16,856 ft² + 3,795 ft² = 20,651 ft².
Now, we divide the total area by the coverage of one gallon of paint to determine the number of gallons needed: 20,651 ft² / 300 ft² = 68.84.
Since we need whole gallons, we will round up to the nearest whole number.
Thus, approximately 69 whole gallons of paint would be needed to paint the two-story house.
