For this case we have that by definition, the volume of a parallelepiped is given by:
[tex]V = l * w * h[/tex]
Where:
l: It's the long
w: It is the width
h: It's the height
From the figure we have the following data:
[tex]V = 975 \ ft ^ 3\\h = 9 \ ft\\w = 4ft\\x =?[/tex]
We must find the value of the length of the parallelepiped:
[tex]975 = x * 4 * 9\\975 = 36x\\x = \frac {975} {36}\\x = 27.083[/tex]
Answer:
[tex]x = 27.1 \ ft[/tex]
