The internal dimension f the box are 1.2m ,80 cm,50 cm,.how maany cubes of 7 cm can be packed with the faces parallel to the side of box and also find the empty space

Answer 1

1.2 m is the same as 120 cm. In 120 cm, we can fit 17 cubes along that side (7 * 17 = 119 so there will be 1 cm left as dead space).

Along the 80 cm side, we can fit 11 cubes (7 * 11 = 77 so there will be 3 cm of dead space along that side).

Along the 50 cm side, we can fit 7 cubes (7 * 7 = 49 so there will be 1 cm of dead space along that side).

That means we can fit 17 x 11 x 7 cubes in the space. Multiply these together to get the answer.
