Answer 2

Answer:

mark me as  brainliest

Step-by-step explanation:

LCM of sides that is 5 cm , 2 cm,5 cm = 10

number of cuboids = Volume of cube / Volume of cuboid

                                             10 cm ,10 cm,10 cm/ 5 cm,2 cm ,5 cm

                                             (5*2*2)

                                            =20 cuboids answer
