Find a mass that is 4 times more than 2 kg 400 g.

With the help of the conditional variable “Y” we denote the desired mass, which is 4 times more than 2 kg 400 g.

Knowing that 1 kilogram contains 1000 grams, and using the conditions of the problem, we form the following equation: Y = 4 x (2 x 1000 + 400).

As a result of solving this equation, we will have the value Y = 4 x (2000 + 400) = 4 x 2400 = 9600 grams or 9 kg 600 g.

Answer: 9 kg 600 g.
