How many wooden cubical blocks of edge 20 cm can be cut from a log of wood of size 8m by 5m by 80 cm, assuming there is no wastage.



It's once again the same type of question.
you just have to convert meter into centimeter.
so, volume of cube= 20 x 20 x 20 = 8000 cm^3
volume of cuboidal log of wood = 800 x 500 x 80 = 32000000 cm^3
now divide, 32000000 / 8000 = 4000
so the answer is 4000 cubes
