Question

Rahul makes a cuboid of plasticine of sides 3cm×3cm×5cm. how many such cuboids will he need to form a cube?​

Answer 1

Answer:

75.

The volume occupied by one cuboid is 45 = 3*3*5.

Look at this as a number 45. The multiple of 45 which is a perfect cube is equal to 45*3*5*5, which is equal to 3*3*3*5*5*5.

So number of cuboids = 5*5*3 = 75.

● If triplets are not there we should multiply the numbers such as there is a pair of 3 and single 5 so one 3 is less from its triplet and pair of 5 is less from its triplet. Therefore 75 number of cuboids are necessary to form a cube.
