Question

Sunil makes a cuboid of plasticine of sides 5 cm, 4 cm, 2 cm. How many such cuboids will be needed to form a cube?​

Answer 1

Answer:

needed =volume

volume of cuboid=5×4×2

now split each number to group them

=5×1×2×2×2

as volume is of three same pairs we got three 2's

so we need two more 5's to make a cubic

now it is 5×5×5×2×2×2

by cubing =5×2

10 cuboids will be needed
