I want to know how many bricks and cement it would take to build the following brick wall: the bricks are 16 inches by 8 inches, and the wall would measure 6 ft high by 200 ft long...

Sagot :

[tex]First\ we\ should\ calculate\ Area\ of\ the\ wall:\\\\ A=6*200=1200ft^2\\\\ Secondly\ calculate\ area\ of\ one\ brick\\\\ a=16*8=128ft^2\\\\ Dividing\ Area\ of\ wall\ by\ area\ of\ brick\ we \ will\ find\ number\\ of\ bricks:\\\\ \frac{A}{a}=\frac{1200ft^2}{128ft^2}= 9,375\\\\ It \ would\ take\ about\ 10 \ bricks.
