A block of wood is in the form of a cube whose edge is 7 m. How many small rectangular blocks of size 25 cm*8 cm*5 cm* can be cut from the block, if there is no wastage of wood?

  • math -

    7m = 7000cm

    7000/25 = 280
    7000/8 = 875
    7000/5 = 1400

    SO, there are 280*875*1400 = 343000000 blocks
