Question

Define a method calcPyramidVolume with double data type parameters baseLength, baseWidth, and pyramidHeight, that returns as a double the volume of a pyramid with a rectangular base. calcPyramidVolume() calls the given calcBaseArea() method in the calculation. Relevant geometry equations: Volume

Answer 1

Answer:

import java.io.*;

public class Main {

   public static void main(String[] args) throws IOException {

       double baseLength = 0, baseWidth = 0, pyramidHeight = 0;

       Object[] volume;

       volume = calcPyramidVolume(baseLength, baseWidth, pyramidHeight);

   }

   public static Object[] calcPyramidVolume(double baseLength, double baseWidth, double pyramidHeight) {

       double area = calcBaseArea(baseLength, baseWidth);

       double volume = baseLength * baseWidth * pyramidHeight;

       return new Object[]{volume, area};

   }

   public static double calcBaseArea(double length, double width) {

       return length * width;

   }

}

Explanation:

The problem is flawed because it is completely inefficient for one to create two separate methods to calculate the volume and the area when they can be done at once.

The second problem is that it was never specified whether to return something from the calcBaseArea method.

I assumed it required it, so it is not advisable to initiate the method as a double, but rather create it as an Object so that it can return two values: the volume and the area.
