SOLUTION
From the question we want to know how many cubic-feet of a warehouse can contain 430 boxes, whereby "each one" of these 430 boxes measures 12 inches by 8 inches by 9 inches
Firstly we have to change these inches of the sides of ecah of these boxes to feet.
12 inches make a foot.
Hence each box in feet will measure
[tex]\begin{gathered} \frac{12}{12}ft\times\frac{8}{12}ft\times\frac{9}{12}ft \\ =1\times\frac{2}{3}\times\frac{3}{4} \\ =\frac{2}{4} \\ =\frac{1}{2}ft^3 \end{gathered}[/tex]So each boxes in feet will measure half cubic foot.
The warehouse that will contain 430 of these boxes should measure
[tex]\begin{gathered} 430\times\frac{1}{2} \\ =215ft^3 \end{gathered}[/tex]Hence, the answer is 215 cubic-feet
