Lesson 17 : More or less

Do you think a cube has the same volume as a cuboid?











How many 1cm*1cm*1cm cubes are needed to fill the 4cm* 4cm*4cm and the 8cm*4cm* 2cm?






Volume =  length* width*height
             =  5cm*3cm*3cm*
             =  45cm cube






Volume =  length* width*height
             =  8cm*2cm*4cm*
             =  64cm cube
