Question

a brick measures 30cm×10cm× how many bricks will be required for a wall 30m long 2 high and thick

Answer 1

Answer:

I found 25,000 bricks.

Explanation:

I evaluated the volume of the wall V and divided by the volume v of one brick (in cubic meters):

Vv=30×0.5×2.50.2×0.1×0.075=37.50.0015=25,000 bricks.

It seemed a lot but then I noticed that the bricks are small or at least smaller than the usual ones.
