Answer :
Space between each shelf and the next is equals to 9inches while constructing set of eight shelves.
What is space?
" Space is defined as the area left between two given object."
Conversion used
1ft = 12inches
According to the question,
Set of bookshelves to be constructed = 8
Floor to ceiling clearance = 7ft 5in.
= (7 × 12 + 5)inches
= 89 inches
Thickness of each shelf = 1inch
'x' represents the equal space left between the shelves top and the ceiling.
Therefore,
Total space left between the 8 shelves top and the ceiling = 9x
From the given data and condition we have,
Total space left + (set of shelves × thickness) = Floor to ceiling clearance
⇒9x + 8× 1 = 89
⇒[tex]9x + 8 = 89[/tex]
⇒[tex]9x = 89 -8[/tex]
⇒[tex]9x = 81[/tex]
⇒ [tex]x=\frac{81}{9}[/tex]
⇒[tex]x=9[/tex] inches
Hence, space between each shelf and the next is equals to 9inches while constructing set of eight shelves.
