Question

if a cuboid. has sides 5*2*5then how many cuboids are needed to make a cube

Answer 1

to solve this question,first find the area of the cuboids

5x2x5=75cmcube

we see that the prime factor form of 75 is5x2x5

thus,by our common sense we can make out that to get a perfect cube,we must multiply 75 by 45

thus, 45 is the smallest no of cuboids to make a cube with intergral edges
