You want to apply two coats of paint to walls that are 8 ft high in a room that is 7 11/12 feet wide and 9 5/6 feet long. One gallon of paint covers 350 square feet.

Paint required will be 2.06gallons

Step-by-step explanation:

The given dimensions are

Height - 8ft

Width - 7 = 7.9ft

Length - 9. 83ft

To calculate the the amount of paint required to paint the walls we need to find the area of the walls

wall 1  = height * width of room= 8 * 7.9 = 63.28

wall 2 = height * length = 8*9.83 = 78.64

The total area of the 4 walls will be = 2*(63 .28+78.64)= 283.84

ceiling area = 77.66

total area to be painted = 283.84 + 77.66 = 361.50

One gallon of paint covers 350 of area

so 361.50 area will be covered by = 361.5/350 = 1.03gallons of paint

also we need two coating so the paint required will be = 1.03 * 2 =2.06gallons
