Thanks to all of you who attempted to solve this extra credit problem. Here’s how it was graded 3 points for attempting it, 7 points for most of it right, 10 points for a correct response.

So how do you solve this one? The same way we did the investigation on class. You needed to solve for volume:

V=LxWxH

L= length of the building in meters (same as you used in class)

W= width of building in meters (same as you used in class)

H= depth of rain in meters (remember you have to use all the same units)

1.5 inches per hr for .5 hrs = .75 inches. Convert this to meters multiply by 2.54 (number of cm in 1 inch, the conversion is listed in your planner) then divide by 100 to convert to meters (100cm in a meter).

H=.75 x 0.0254 =0.01905 (round to .002m)

V=60x30x.002=36 cubic meters

convert cubic meters to liters multiple by 1000

36×1000=36,000 L

Divide by 220L per barrel

36,000 / 220 = 163.6 barrels

Sounds like a lot to do but we did almost all of this in class and it should have been in your notes.

Good notes pay off.

Tomorrow is fine. All classes were given an extra day to complete the extra credit. Tomorrow is fine.
