Question

how many cubes having edge 3cm can be cut from a cube having edge of 6cm?

Answer 1

volume of cube=side³
 so ,first we find volume of small cube=[3]³  =>  27cm
       second, the volume of larger cube = [6]³  =>  216cm
 
  to found number of 3cm cubes which were formed by cut the 6cm cubes--->
                                volume of larger÷volume of smaller
                     =>              216 ÷ 27=8
                   =>                8 cubes had been made from larger cube
                                                                                               plz mark it best
