20 cuboids

Therefore, 20 cuboids each of sides 5 cm, 2 cm, 5 cm will be needed to form a cube.

Answer 2

Answer:

hope it hepls u

Step-by-step explanation:

L.C.M. of 5 and 2 gives the dimension of the cube to be formed.

L.C.M. of 5 and 2 is 10.

Volume of cuboid =5×5×2=50${cm}^3$

Volume of bigger cube = $10^3 =1000cm^3$

Number of cuboids required to make the bigger cube =

$\frac{(Volume of cube)}{(Volume of cuboid)} =\frac{1000}{5} = 20$
