Answer:
The size of the cube so formed is 8 cm.
Step-by-step explanation:
Given : A cardboard of size 16cm× 24cm has been completely used to form a cube.
To find : What will be the size of the cube so formed?
Solution :
Surface area of cardboard is
A = l * w
A= 16 * 24 '
A= 384 cm²
Now, Surface area won't change, when it will transform into a cube so,
Surface area of cube is
A=6a²
So,
6a² = 384
a² = 384/6
a² = 64
a = √64
a = 8
Therefore, The size of the cube so formed is 8 cm.
