Question

find the number of cuboids of sides 5cm, 3cm and 5cm required to form a cube

Answer 1

Hmm...

Volume of the Cuboid With Given Dimensions=
5×5×3=75cm³

now...

The Smallest Measurement of the side of a Cube From the given Dimensions is 3cm But Since Cube cant be Smaller than cuboid (in this case) So the Samallest value of a side of cube=5cm

Now Volume of Cube=125cm³

on comparing 75 and 125

we can see

75/25=3
125/25=5

now

125×3=375
and 75×5=375


So 5 Cuboids of the Given Dimension are Required to make a Cube....

i hope you Understand...
