**Ms. Sue**, Thursday, June 14, 2012 at 6:10pmFirst find the volume of the wall.

V = LWH

Find the volume of each brick.

Then convert that to cubic centimeters.

1 cubic meter = 1 000 000 cubic centimeters

**Leo**, Thursday, June 14, 2012 at 6:21pmvolume of wall is 2.7

vol of each brick= 900

900,000,000

Is that how many bricks? Sounds like alot. Am I missing a step

**Ms. Sue**, Thursday, June 14, 2012 at 6:28pmRight -- the volume of the wall is 2.7 cubic meters = 2,700,000 cubic centimeters

Each brick's volume is 900 cubic centimeters.

Here's your mistake. You need to divide, not multiply.

2,700,000 / 900 = 3,000 bricks
