Question

And made a cuboid with dimensions 10cm, 7cm and 2c. What is the least number of such cuboid needed to form a cube?

Answer 1

Take the L.C.M of dimensions:
 = 2 × 5 × 7 = 70
Volume of such cubes = 70 × 70 × 70 = 343000 cm³
Volume of original cuboid = 10 × 7 × 2 = 140
Then, Number of cuboids required = 343000/140 
                                                        = 2450

Answer 2

Answer:

To make it a perfect cube we multiply by 2 * 5² *7² . Number of such cuboids required = Volume of Cube / Volume of cuboid = 343000/140 = 2450 . Therefore number of least such cubiods Anu would require to make a cube is 2450 .
