Question

how many cubes if 5cm can fit inside a cube of 1cm

​

Answer 1

Answer:

Let the side of original cube=x1=5 cm

Surface area of original cube =A1=6x12

∴A1=6×52=6×25cm2

Now, length of side of new cube =x2=1 cm

Surface area of new cube =A2=6x2 2

∴A1=6×12=6×1=6cm2

∴ A2

A1. =66×25=125

∴A1 :A2 =25:1
