Answer:
Step-by-step explanation:
L.C.M. of 5,2=10
so it should be of dimensions 10×10×10
it should have 5 cuboids in first row.
then it will make a cuboid 5×10×5
5 cuboids in the second row on top of first row .
Then it will make 5×10×10 cuboid
To make 10×10×10
double the cuboids to make the length=10 and height=10..
so in all 20 cuboids are needed.
2 rows of 5 cuboids on the floor and 2 rows of 5 cuboids on the top.
in all 10 cuboids of dimensions 5×2×5
so 9 more cuboids are needed to make a c
