Step-by-step explanation:
LCM of 5,4,2=20
no of cuboids =20 X 20x20/ volume of cuboid
=
20 X 20 x 20/ 5 x 4 x 2
=200
no of cuboids required to Prepare cube = 200

Given: The dimensions of the cuboid are 5 cm, 4 cm, 2 cm.
To find: The number of cuboids needed to form a cube
Solution: To find the dimensions of the required cube, we need to calculate the LCM of the dimensions of the cuboid.
As such, the LCM of 5, 4 and 2 = 20.
Therefore, the area of the cube = 20³ cm³ = 8000 cm³.
The area of the cuboid = 5 × 4 × 2 cm³ = 40 cm³.
Hence, the number of cuboids needed to form a cube
= 8000/40 = 200.
Answer: 200
