/* Formula for volume is LxWxH. Multiply the input by itself three times! Or use the Math.pow method(). */ //Lets grab the span ids and store them into variables for later use var length = document.getElementById("length"); var answer = document.getElementById("answer"); //Ask the user for an input and store into a variable var side = prompt("Enter the length/height/width of your cube", 2); //calculate the volume - Method 1 //var volume = side * side * side; //console.log("side: " + side + " volume: " + volume); length.innerText = side; //calculate the volume - Method 2 var volume = Math.pow(side,3); answer.innerText = volume;

<!-- Easy JavaScript #9 - Calculate Volume of a Cube --> <p> How do you get the volume of a Cube? You multiply the length, width, and height. </p> <p> Since it's a cube, you will only need to get one number. </p> <p> One side of your cube has a measurement of <span id="length">___</span> units. </p> <p> Your cube has a volume of <span id="answer">___</span> units cubed. </p> <p> Visit <a href="http://www.easyprogramming.net">EasyProgramming.net</a> for more tutorials! </p>
