The volume of a wall, 5 times as high as it is broad and 8 times as long as it is high, is 12.8 cu. meters. Find the breadth of the wall.  Choices
A) 40
B) 29
C) 28
D) 27
E) 12
Explanation:   Let the breadth of the wall be x metres.   Then, Height = 5x metres and Length = 40x metres.   x * 5x * 40x = 12.8   =&gt;\inline \fn_jvn x^3=\frac{12.8}{200}=\frac{128}{2000}=\frac{64}{1000}   =&gt;\inline \fn_jvn x=\frac{4}{10}m   =&gt;\inline \fn_jvn x=\frac{4}{10}\times 100=40cm   40nswer: 40) 40cm
