The formula for Rectangular Solid is :

hba · Answer

V=lwh < Thats it @waterineyes

anonymous · Answer

Volume = Length x Width x Height..

hba · Answer

Yeah.

anonymous · Answer

Ha ha ha ha..

My equation editor is not working..

hba · Answer

Oh lol :D

anonymous · Answer

Let the previous dimensions were : l, w and h...

hba · Answer

So do i have to differentiate it ?

anonymous · Answer

And now they are decreased by 50 %...

hba · Answer

yeah so ?

anonymous · Answer

l - 50% of l,       w - 50 % of w,         h - 50% of h         these are now new dimensions..

anonymous · Answer

i.e 1/2l,     1/2w,   1/2h   are now new dimensions..

hba · Answer

Please get to the point ?

anonymous · Answer

From previous values : lwh = 1000


Now new volume : 1/8 (lwh) = V

1/8 x 1000 = V

Now find V..

Thanks Alot.
