Ruby program to calculate the volume, diagonal, and area of Cuboids

Program/Source Code:

The source code to calculate the volume, diagonal, and area of Cuboids is given below. The given program is compiled and executed successfully.

# Ruby program to calculate the 
# volume, diagonal, and area of Cuboids

length=0.0;
height=0.0;
width =0.0;

diagonal=0.0;
volume=0.0;
area  =0.0;

print "Enter length: ";
length = gets.chomp.to_f;  

print "Enter height: ";
height = gets.chomp.to_f;  

print "Enter width: ";
width = gets.chomp.to_f;  

diagonal = Math.sqrt((width * width)) + (length * length) + (height * height);
area     = 2.0 * (width * length) + (length * height) + (height * width);
volume   = width * length * height;

print "Diagonal of Cuboids  is: ",diagonal;    
print "\nVolume of Cuboids  is: ",volume;
print "\nArea of Cuboids  is: ",area;

Output:

Enter length: 12.3
Enter height: 12.5
Enter width: 15.4
Diagonal of Cuboids  is: 322.94000000000005
Volume of Cuboids  is: 2367.75
Area of Cuboids  is: 725.09

Explanation:

In the above program, we created six variables length, height, width, diagonal, volume, area that are initialized with 0.0. Then we read length, height, width of Cuboids from the user and calculated the surface area, volume, and diagonal of Cuboids using the standard formula. After that, we printed the result.
