Respuesta :

Answer:

The glass cost for all of the window installations is approx. $518.4

Step-by-step explanation:

The total number of windows in the house = 6

Dimensions of each window = 3 ft by 4 ft

1 ft = 12 inch

Now, AREA of Each window = LENGTH x WIDTH

                                                 = 3 ft x   4 ft  = 12 sq ft

So, the area of each window in the house =  12 sq ft

⇒ Area of 6 windows= 6 x ( area of each window)

= 6 ( 12 sq ft)  = 72 sq ft

So, the combined area of 6 windows in the house  =  72 sq ft

Now,       1 sq ft =  144 sq inches

⇒ Combined area of 6 windows in the house  =  72 sq ft x 144

                                                                               = 10,368 sq inches

Now, cost of glass for per square inch = $0.05

So, the cost of 10,368 sq inches = $0.05 x 10,368 sq inches

                                                        = $518.4

Hence, the glass cost for all of the window installations is approx. $518.4
