Question

What is the height of a rectangular solid with the following dimensions:

Length= 7 feet
Width= 5 feet 
Volume= 105 cubic feet

ganpat · Answer

V = LBH..
So, 105 = 7 * 5 * H

Therefore H = 7 ft...

ganpat · Answer

I have a hint for you.. always look at units first.. they might help you to get the required formula.. 

over here V= Ft3.. so on the other side it should be ft *ft* ft or ft * ft2..

Hope u get this..

thank you

But @Ganpat  if there is a constant value then the answer may be wrong..

anonymous · Answer

Height is not coming out to 7 feet...

ganpat · Answer

@waterineyes :yes.. for constant there may be issues, this is just to get tentative idea on what u r dealing with.. 

and you have take width 7ft.. its actually .. 5ft in question..

anonymous · Answer

Sorry but I have put it right in the formula...

anonymous · Answer

@Ganpat your answer is wrong for height i think...

anonymous · Answer

$$V=Length∗Width∗Height$$

Length = 7
Width = 5
V = 105

So,

$$105=7×5×H$$


$$105=35×H$$

$$H =\frac{\cancel{105}^3}{\cancel{35}^1} = 3$$

Therefore, Height = 3 Feet...

oh sorry.. Visual calculations, lil error.. sorry for that..
@xLynnBbyx: Keep a update of this one, my answer was wrong in calculation..
