The soil borrow material to be used to construct a highway embankment has a mass unit weight of 99.0 lb./cf and a water content of 6.5%, and the specific gravity of the soil solids is 2.65. The specifications require that the soil be placed in the fill so that the dry unit weight is 112 lb./cf and the water content be held to 6%. A. How many cubic yards of borrow are required to construct an embankment having a 600,000-cy net section volume?
B. How many gallons of water must be added per cubic yard of material assuming no loss evaporation?
C. If the compacted fill becomes saturated at constant volume, what will be the water content and unit weight?

answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

//main function

int main()

{

  // variable

 int n;

 cout<<"enter a number:";

 // read the input

 cin>>n;

 // find the square root of the absolute value

 float square_root=sqrt(abs(n));

 // print the square_root

 cout<<"square root of "<<n<<" is: "<<square_root<<endl;

  return 0;

}

Explanation:

Read a number from user and assign it to "n".Then find its absolute value with abs() function.Then calculate the square root of the absolute value with sqrt() function.Print the square root of the number.

Output:

enter a number:-17

square root of -17 is: 4.12311
