In a rectangular room 10 ft wide 40 ft long and 15 feet high there are four Windows each 30 in by 48 in what is the ratio of window surface to floor area in this room?
To find the ratio of window surface area to floor area in the given room, we need to calculate the total surface area of the windows and the floor separately.
First, let's find the surface area of the windows:
Since there are four windows, we need to calculate the area of one window and then multiply it by four.
The dimensions of each window are given as 30 inches by 48 inches. However, it's better to convert them to feet to maintain consistency with the room's measurements.
30 inches ÷ 12 inches/ft = 2.5 feet
48 inches ÷ 12 inches/ft = 4 feet
Now we can calculate the area of one window:
Area of one window = length × width = 2.5 ft × 4 ft = 10 square feet
Since there are four windows, the total window surface area is:
Total window surface area = 10 sq ft × 4 = 40 square feet
Next, let's calculate the floor area of the room:
The dimensions of the room are given as 10 ft wide, 40 ft long, and 15 ft high. To find the floor area, we multiply the length by the width:
Floor area = length × width = 10 ft × 40 ft = 400 square feet
Finally, we can find the ratio of window surface area to floor area:
Ratio = Window surface area ÷ Floor area
= 40 sq ft ÷ 400 sq ft
= 0.1
Therefore, the ratio of window surface area to floor area in this room is 0.1.
area of floor = (10(40) ft^2 = ....
area of one window = (30in)(48in)
= (2.5)(4) ft^2 = ....
so you have 4 of those, .....
ratio of window : floor = .....
I still dont get it I have to see things drawn out out piece by piece just how I learn
Ok, then, draw your room and the windows, put in the data and follow
my calculations.
I can't make it any simpler.
