7. How many wooden cubical blocks of edge 20 cm can be cut from a log of wood of size 8 m by 5 m bu80 cm, assuming there is no wastage.

Answer»

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 = 4000So 4000 cubes
