do you know the formula to surface area?

anonymous · Answer

x^2 = (500 / h )

anonymous · Answer

No i do not know the formula

anonymous · Answer

This is the answer my teacher got.

superhelp101 · Answer

surface Area of Rectangular Prism: S = 2(lw + lh + wh

anonymous · Answer

so this is the equation for surface area?

superhelp101 · Answer

yeah for a rectangular prism

anonymous · Answer

ok so what do we do first?

anonymous · Answer

I know the width is going to be x^2

superhelp101 · Answer

yeah and we know the volume is 500 
and we have to solve for h first

anonymous · Answer

right

superhelp101 · Answer

so in the formula you have to mult all the numbers in the paratheses twice so u multi. 2 by x^2
to get 2x^2 like you teacher got

anonymous · Answer

i get that part but I don't know how she got 2000/x

superhelp101 · Answer

ikr where did that come from ???

anonymous · Answer

I know right, she must've made mistake
