Well, an object's weight on earth is its mass times 9.80 N/kg. 
So, 34N = (mass)(9.80N/kg) 
Divide both sides by 9.80 to get..... 
mass = 3.47kg. 
 So the correct answer is 3.47 kg  
Hope this helped! :)

Answer: Option (a) is the correct answer.

Explanation:

It is known that weight is equal to mass times acceleration due to gravity.

Mathematically,           Weight = mass × acceleration due to gravity

Since, it is given that weight is 34 N and it is known value of g is 9.8 m/s.

Therefore, calculate mass of the box as follows.

                    Weight = mass × acceleration due to gravity

                       34 N = mass × 9.8 m/s

                     mass = 3.47 kg

Hence, we can conclude that mass of the box is 3.47 kg.
