One paint container is enough to paint all the faces of fifty 8 cm cubes.
Given
The paint can cover 20,000
Side of square = 8 cm
As the Total surface area of a cube is ,
where a is the side of the cube.
The total surface area of one cube = 6 x
= 384
Since there are fifty such cubes,
384 x 50
Total area to be painted = 19200
Since 19,200 is less than 20,000
, it is possible to paint all the cubes.
Hence one paint container is enough to paint all cubes.
