Aballet class of 10 dancers uses a discarded shipping container as a temporary classroom. the walls, floor, and roof of the container are made of the same uniform material, and the container measures 10 feet x 10 feet x 30 feet. on a day when the air temperature is 30°f and the ground temperature is 40°f, determine the minimum r-value of the container in order to maintain a constant interior temperature of 65°f. assume each of the 10 dancers outputs 600 btu/hr of metabolic heat and no additional heat source is available.

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
