Question:
Question 2: A cuboid has dimensions 5cm , 2cm, 5cm .How many such cuboid will be needed to form a cube?
Answer:
Given cuboids of dimensions 5 cm, 2 cm ,5 cm
LCM(5, 2, 5) = 10
Since 5*2 = 10
2*5 = 10
and 5*2 = 10 {since a cube has all the dimensions are same}
So, the number of cuboids required to form a cube = 2*5*2 = 20
So, by using 20 cuboids, we can form a cube having side 10 cm each.
