Question

write the programs in java using Given value:
3. print the cube and twice of 20.​

Answer 1

Solution:

Program to print cube and twice of 20 is given below –

public class Program {

public static void main(String[] args) {

int a=20;

int twice=a*2;

int cube=a*a*a;

System.out.println("Cube of 20: "+cube);

System.out.println("Twice of 20: "+twice);

}

}

Logic:

• Store 20 in a variable - a.
• Multiply a by 2 and store the result in variable - twice.
• Store the cube of a in another variable - cube.
• Display the values of the variables - twice and cube.

See the attachment for output.

Answer 2

Answer:

class Display {

public static void main (String ar []){

int a=3,b=20;

System.out.println("Cube of 3:"+(Math.pow(a,3)));

System.out.println("Twice of 20:"+(b*2));

}

}

• You can also use (a*a*a) instead of Math.pow(a,3)
• pow() is for number raisedto power other number
