Answer 1

Answer:

20 cubes

Step-by-step explanation:

no.of cube= volume of cube

volume of cuboid

Now,

we have to find the LCM of 5,2,5= 10

so,the each side of cube is 10cm.

The volume of cuboid=5×2×5 cubic cm

=50 cubic cm

and the volume of new cube =10*10*10

=1000 cubic cm

no.of cube=1000

50

=20 cube.
