HOW MANY CUBOIDS OF DIMENSIONS 4CM, 6CM,15CM ARE NEEDED TO MAKE A CUBE

If u mean- "**A cuboid has dimensions 4cm, 6cm, 15cm. what is the minimum number of cuboids required to make a cube?"**

Then,

Given, dimensions of cuboid are 4 cm, 6 cm and 15 cm.

L.C.M. of 4, 6 and 15 is 60.

Since, 4 × 15 = 60

6 × 10 = 60

And, 15 × 4 = 60

Hence, the number of cuboids required to form a cube = 15 × 10 × 4 = 600.

Hence, by using 600 cuboids, we can form a cube with side 60 cm each.
