Answer:

So, by using 4 cuboids, we can form a cube having side 30 cm each. This discussion on How many cuboids of dimensions 15cm, 30cm ,15cm will be needed to form a cube ? a)15b)4c)30 d)5Correct answer is option 'B'.

Answer 2

Answer:

Four cuboids.Putting them in a block formation will cause each side to be of 15 cm

Step-by-step explanation:

L.C.M. of 15, 30 and 15 is 30.

Since 15 × 2 = 30

30 × 1 = 30

and 15 ×2 = 30

Hence, the number of cuboids required to form a cube = 2 × 1 × 2 = 4.

Hence, by using 4 cuboids, we can form a cube with side 30 cm each.
