Question

Rahul makes a cuboid of plasticine of sides 5cm,2cm,5cm.how many such cuboid will he need to form a cube?​

Answer 1

Answer:

20 cuboids

Step-by-step explanation:

If height is considered 2 cm, and length is considered 5 cm, then, 5 blocks stacked on top of each other will give the height of cube and 2 blocks next to each other will give the breadth and length to give a cube of sides 10×10×10 cm

Hope this helps!

Answer 2

let's do prime factorisation of 5,2,5

if we take prime factorisation, then 5×5 ×2×2 = 100

5×2×5=50

100÷50= 2

so , he need 2 more such cuboids to form cube
