How many square feet of material are required for 8 windows, with 6 measuring 30" x 48" and 2 measuring 18" x 48" each?

To determine the total square footage of material required for the windows, we need to calculate the area of each of the windows and then sum those areas.

First, let's calculate the area of the six windows measuring 30 inches by 48 inches. The area of one window is calculated as follows:

[

\text{Area of one 30" x 48" window} = \frac{30 \text{ inches}}{12} \times \frac{48 \text{ inches}}{12} = 2.5 \text{ feet} \times 4 \text{ feet} = 10 \text{ square feet}

]

Since there are six of these windows, we multiply this area by six:

[

\text{Total area for six windows} = 6 \times 10 = 60 \text{ square feet}

]

Next, we calculate the area of the two windows measuring 18 inches by 48 inches in the same manner:

[

\text{Area of one 18" x 48" window} = \frac{18 \text{ inches}}{12} \times \frac{48 \text{ inches}}{12} = 1.5 \
