Prime factorisation

(So that we can find the number to multiply to get perfect cube)


so the prime factors are 3 , 3 and 5

We must have triplets in the factors.If triplets are not there we should multiply the numbers such as there is a pair of 3 and single 5 so one 3 is less from its triplet and pair of 5 is less from its triplet.


So multiply these numbers 3*5*5=75


Therefore 75 number of cuboids are necessary to form a cube.
