original box
x (2x)(5x) = 80
x^3 = 8
so
x = 2
2x = 4
5x = 10
now new box
4 * 6 * 12 = 288 cm^3
increase = 288 - 80 = 208
a box whose volume is 80cubic cm has
length,width and height in the ratio
1:2:5 if each of the length,width,height is increased by 2cm how many cubic centimeters will the volume be increased?/
