Program in JAVA code: import java.util.*; //importing util package to get the scanner class,can also have import.java.scanner public class Volume{     public static void main(String []args){        Scanner s = new Scanner(System.in); //creating the scanner to allow INPUT of data                System.out.println("Please enter the unit(cm,m.mm,etc): ");        String u=s.next(); //assigning the unit to the VARIABLE u                System.out.println("Please enter the length: ");        DOUBLE l=s.nextDouble(); //assigning the lenght to the variable l                System.out.println("Please enter the breadth: ");        double b=s.nextDouble(); //assigning the breadth to the variable b                System.out.println("Please enter the height: ");        double h=s.nextDouble(); //assigning the height to the variable h                double vol=l*b*h; //calculating the volume which is lenght by breadth by height(LxBxH) and assigning it to the variable vol                System.out.println("The volume is: "+vol+" "+u+" squared"); //printing the volume     } } //you can copy and paste the code into an online java compiler to make changes etc. Hope i was a GOOD help!
