Bonnie has a container in the shape of a rectangular pyramid. The formula for the surface area of the enclosed space is S = lw + 0.5Ph. Solve for P. P = S – lw – 0.5h P = S + lw + 0.5h P = The quantity S minus l times w all divided by 0.5 times h P = S divided by the quantity l times w plus 0.5 times h

First take Iw to the left hand side.

3. Sachintha

Give it a try.

4. anonymous

i have tried, but I suck :( @Sachintha do you think you could walk me through it?

5. Sachintha

For the first step you remove Iw by the right hand side by subtracting Iw from both sides. $S - Iw = Iw+0.5Ph-Iw$

6. Sachintha

So Iw on right hand side cancel out.

7. anonymous

ok

8. Sachintha

Then you are left with, $S-Iw=0.5Ph$

9. anonymous

ok. next would you add Iw to the other side? to cancel out?

10. Sachintha

No. What we are trying to do is to get an equation for P. So P is left at right hand side.

11. anonymous

O.K!?

12. Sachintha

Finally you divide both sides by 0.5h. $\frac{S-Iw}{0.5h}=\frac{0.5Ph}{0.5h}$ $P=\frac{S-Iw}{0.5h}$

so c?

14. Sachintha

Yeah you are correct. :)

15. Sachintha

Hope you understood every step.

16. anonymous

Thank you so much!
