C. The surface -area -to-volume ratio of the leaf is very high to maximize CO 2 intake

Following are the code to this question:

Explanation:

//For Solid:

public class Solid//defining a class Solid

{

private String myName;//defining a String variable

public Solid(String name)//defining parameterized constructor

{

myName = name;//holding String value in myName variable

}

public String getName()//defining getName method  

{

return myName;//return value of myName

}

public double volume()//defining method volume that overriden its subclass

{

return 0;//return value

}

public double surfaceArea()//defining method surfaceArea that overriden its subclass

{

return 0;//return value

}

}

//For RectangularPrism:

public class RectangularPrism extends Solid//defining a class RectangularPrism that inherits Solid

{

  protected double length,width,height;//defining double variable

RectangularPrism(String str,double l,double w,double h)//defining parameterized constructor

{

  super(str);//use super method

  this.length=l;//use this to hold value

  this.width=w;//use this to hold value

  this.height=h;//use this to hold value

}

public double volume()//defining volume method  

{

return length*width*height;//calculate and return volume value

}

public double surfaceArea()//defining a  method surfaceArea  

{

return 2*(length*width+width*height+height*length);//calculate and return the surfaceArea

}

}

// For  Cube:

public class Cube extends RectangularPrism//defining Cube class that inherits RectangularPrism  

{

  Cube(String name, double side) //defining parameterized constructor

   {

       super(name, side, side, side);//use super method

   }

  public double volume()//defining volume method  

  {

   return length * length * length;//calculate and return volume

  }

public double surfaceArea()//defining method surfaceArea  

  {

  return 6 * length*length;//calculate and return surfaceArea

   }

}

//for Cylinder:

import java.lang.*;//import lang package  

public class Cylinder extends Solid//defining Cylinder class that inherits Solid

{

  private double radius, height;//defining double variable

  public Cylinder(String str, double r, double h)//defining parameterized constructor

  {

      super(str);//use super Method

      this.radius = r;//use this keyword to hold value

      this.height = h;//use this keyword to hold value

  }

  public double volume()//defining volume method

  {

      return Math.PI * radius * radius * height;//calculate and return volume

  }

  public double surfaceArea()//defining surfaceArea method

  {

     return 2 * Math.PI * radius * (height + radius);//calculate and return surfaceArea

  }

}

//For Pyramid

import java.lang.*;//import package

public class Pyramid extends Solid//defining a Pyramid class that inherits Solid

{  

  private double length, width,height;//defining double variable

  public Pyramid(String str, double l, double w, double h)//defining parameterized constructor  

  {

      super(str);//use super method

      this.length = l;//use this keyword to hold value

      this.width = w;//use this keyword to hold value

      this.height = h;//use this keyword to hold value

  }

public double volume()//defining volume method

{

return (length*width*height)/3.0;//calculate and return volume

}

public double surfaceArea()//defining a method surfaceArea

{

return (length*width)+length*Math.sqrt((Math.pow((width/2),2)+(height*height)))+(width*Math.sqrt((Math.pow((length/2),2)+(height*height))));//calculate and return surfaceArea

}

}

//For Sphere

import java.lang.*;//import package

public class Sphere extends Solid //defining Sphere class that inherits Solid

{

  private double radius;//defining double variable

  public Sphere(String str, double r)//defining parameterized constructor  

  {

      super(str);//use super method

      this.radius = r;//use this to hold value

  }

  public double volume()//defining volume method

  {

      return (4.0/3.0)*Math.PI*radius*radius*radius;//calculate and return volume

  }

  public double surfaceArea()//defining method surfaceArea  

  {

    return 4 * Math.PI * radius * radius;//calculate and return surfaceArea

  }

}
