Any ideas?

Not really... I'm fine with finding height but finding width is my weak spot.

skullpatrol · Answer

Recall the formula for the volume of a rectangular prism is V = l*w*h

anonymous · Answer

I am pretty sure it is 6...

anonymous · Answer

But try entering the possible answers into the equation.

anonymous · Answer

$$288=6*8*width$$
$$288=48*width$$
$$\frac{ 288 }{ 48 } = width$$

anonymous · Answer

Ok... Thanks. I'll try working off of the information everyone gave me.

anonymous · Answer

I believe the answer is 6...

Correct :-)

Not just 6. 

6*(1 foot) = 6 feet.
