sergejj [24]

The total age of the three children are = 37years

<h3>Calculation of the total age of children</h3>

child 2 = x

child. 3 = x

Therefore, the age of three children = x³= 1872

Therefore;

x =  \sqrt[3]{1872}

X = 12.32448

The age of the middle child = 12.32448 + 12.32448

= 24.64896/2

= 12.32448

Therefore the sum of their ages = 12.32448 + 12.32448 + 12.32448 = 37years.
