A contractor orders, say, 30 cubic yards of premixed concrete to construct a patio that is to be, say, four inches thick.

The length of the patio is to be, say, twice the width. Write a program that prompts the user to specify:

  1. The amount of premixed concrete (in cubic yards) ordered
  2. The thickness of the patio (in inches)
  3. The ratio of length and width.

Ex. If the ratio is 3 to 2, have the program accept a 3 then a 2. Then compute the ratio using these numbers.

The program then outputs:

The length and width of the patio (in feet). (1 cubic yard = 27 cubic feet.)

To find the square root of a decimal number, include the header file cmath using the statement #include, in your program.

The function sqrt, included in this header file, determines the square root of a decimal number.

      #include <iostream>

#include <cmath>

using namespace std;


int main() {

double premix_concrete, thickness, length_ratio, width_ratio;

//Inputs

cout<<"Enter the amount of premixed concrete (in cubic yards) ordered : ";

cin>>premix_concrete;

cout<<"Enter the thickness of the patio (in inches) : ";

cin>>thickness;

cout<<"Enter the ratio of length and width : ";

cin>>length_ratio>>width_ratio;

// Get amount of the premix_concrete in (cubic feet)

double premix_feet = 27*premix_concrete;

// Get the thickness in (feet)

double thickness_feet = thickness/12;

// Get the common factor of the ratio

double x = sqrt(premix_feet/(length_ratio*width_ratio*thickness_feet));

// Outputs

cout<<"Length : "<<x*length_ratio<<" feet Width : "<<x*width_ratio<<" feet"<<endl;

return 0;

}
