parikshit makes a cuboid of plasticine of sides 5 cm, 2cm,5cm.how many such cuboida will be needed to form a cube?(urgent)

please give the answer quickly by the explanation!!thank you

volume = length * breadth* height

cube's volume = 2*5*5 cm ^{3 }= 50cm^{3}

write 50 inside the of cube = then write factors of 50 inside the sign of cube

write 1000 inside the sign of cube = 10

so, the smallest number of cuboids needed = 10*2 = 20.
