Question

Accepted Answer

First, find the area (surface) of the ceiling. Since it is opposite the floor, it has the same length and width(A = 1xw).19 feet x 10 feet = 190 square feet (ceiling) Next find the combined area of two matching (opposite) walls. Start with the walls formed by the length and height of the room.(Clear the decimal in the divisor.) 19 feet x 8 feet = 152 square feet (first wall) 152 feet x 2 = 304 square feet (matching walls) Then find the area of the walls formed by the width andheight of the room. 10 feet x 8 feet = 80 square feet (second wall) 80 feet x 2 = 160 square feet (matching walls) Finally, combine all surfaces to be painted. 190 + 304 + 160 = 654 square feet
