Respuesta :

The cans of paint that are needed is 25 cans.

How to calculate the value?

It should be noted that the sides of the cube will be:

= 3✓2197

= 13

Each side is 13m

Therefore, the total surface area will be:

= 6s²

s = sides

= 6(13)²

= 1014m²

Therefore, the cans needed will be:

= 1014/40

= 25

Therefore, 25 cans are needed.
