Just multiply those two numbers together.
8 x 9.5 = 76 feet
(9 ft 6 in = 9 + 6/12 = 9.5, just in case you wondering how I got the 9.5)
That's a nice problem! The room is 5-ft long and 4-ft wide.
Room volume: 10*24*30 = 7,200 cubic feet
-- Two of the walls are 15-ft wide and 10-ft high. Each of them has an area of 150 square ft.-- The other two walls are 18-ft wide and 10-ft high. The area of each is 180 square ft.-- The total area of the walls is (2 x 150) + (2 x 180) = 300 + 360 = 660 square ft.That's what Sally needs to start with, although she'll wind up cutting out and discardingpieces that would otherwise cover the door and windows.
40 ft x 28 ft = 1120 square feet
You cannot have an area of 120 ft. An area must be measured in square units, such as square feet. The answer will be different if the area is 120 ft by 1 ft wide or 10 ft wide or 10 miles wide!
The area is 168ft squared.

Normally the square footage of a room refers to the floor area ad so the height of the room is irrelevant. In this case, the area is 4 ft * 4 ft = 16 square feet.
