325, space, c, m, start superscript, 2, end superscript of his skin.

Answer 1

For this case we can make the following rule of three:
2 ml -------------> 50cm ^ 2
c -----------------> 325 cm ^ 2
From here, we clear the value of c.
We have then:
c = (325/50) * (2)
c = 13 ml
Answer:
I need 13 milliliters of sunscreen to cover his skin.
