    Given diameter of the hole, d = 30 cm

    radius of the hole, r = d/2 = 30/2 = 15 cm

    Height of the cylindrical hole, h = 70 cm

    Volume of the cuboidal block = lbh

    = 70×30×30

    = 63000 cm3

    Volume of cylindrical hole =π r2h

    = (22/7)×152×70

    = 22×225×10

    = 49500 cm3

    Volume of the wood left in the block = 63000-49500 = 13500 cm3

    Hence the volume of the wood left in the block is 13500 cm3.
