Total bookshelf length in the book case = [tex]5\times 42=210\ \text{inches}[/tex]

[tex]1\ \text{feet}=12\ \text{inches}\\\Rightarrow 1\ \text{inch}=\dfrac{1}{12}\ \text{feet}[/tex]

[tex]210\ \text{feet}=210\times \dfrac{1}{12}=17.5\ \text{feet}[/tex]

The bookcase has a total shelf space of [tex]17.5\ \text{feet}[/tex].

Final answer:

To find the total feet of shelf space in the bookcase, we need to convert the length of the bookshelves from inches to feet. Since there are 5 bookshelves and each is 42 inches long, the total length in feet is 17.5 feet.

Explanation:

To find the total feet of shelf space in the bookcase, we need to convert the length of the bookshelves from inches to feet. Since there are 5 bookshelves and each is 42 inches long, the total length in inches is 5 x 42 = 210 inches. To convert inches to feet, we divide the length in inches by 12, since there are 12 inches in a foot. So, the total length in feet would be 210 / 12 = 17.5 feet.
