Bricks wall

There are 5000 bricks. How high wall thickness of 20 cm around the area which has dimensions 20 m and 15 m can use these bricks to build? Brick dimensions are 30 cm, 20 cm and 10 cm.

Result

v =  0 cm

Solution:

V=5000 0.30 0.20 0.10=30 o=2 (20+2 0.20+15)=70.8 M=0.20 o=0.20 70.8=35425=14.16 v=V/M 100=30/14.16 1001250059211.86440 cmV=5000 \cdot \ 0.30 \cdot \ 0.20 \cdot \ 0.10=30 \ \\ o=2 \cdot \ (20+2 \cdot \ 0.20+15)=70.8 \ \\ M=0.20 \cdot \ o=0.20 \cdot \ 70.8=\dfrac{ 354 }{ 25 }=14.16 \ \\ v=V/M \cdot \ 100=30/14.16 \cdot \ 100 \doteq \dfrac{ 12500 }{ 59 } \doteq 211.8644 \doteq 0 \ \text{cm}
