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 = 50cm3

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.

  • 3

5*2*2 = 20

  • -19

it's simple- 5*2*2=20

  • -13

volume of the cuboid = length x breadth x height= 5x2x5=50

check whether 50 is a perfect cube or not by prime factorisation

u will find that 50=5x5x2

so, which no. should be multiplied to 50 so that it bcomes aperfect cube,

we know that 50=5x5x2, so we need one 5 & 2 twos', i.e. 5x2x2,which=20.

therefore ans=20

hope this helps:)
