Spider Crawling up a Web
Problem Statement:
The blue spider just made a web strand going from corner A of a cardboard box to corner D. It now needs to crawl back up to the top. Knowing that the dimension of the box is H x L x W = 12.3" x 8.4" x 5.59", calculate the required traveled distance of the spider and drive the linkbot along the web strand path using driveDistace(). Round to 3 decimals point - tip: to avoid precision error, don't round until the end. 
/* Code generated by RoboBlockly v2.0 */
#include <linkbot.h>
double H;
double W;
double L;
CLinkbotI robot;
double radius = 1.75;

robot.traceColor("green", 3);
H = 12.3;
W = 8.4;
L = 5.59;
// set the %.#lf in printf() for 3 digits after the decimal point for double type
robot.driveDistance(sqrt((H * H + W * W) + L * L), radius);
