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 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.
hope this helps:)
