-The only spaces which are necessary are the line break in the `#include`
-directive and its space between `#include` and `<stdio.h>` as well as the space
-between `return` and `0`.

+The only necessary spaces are:
+
+- the line break in the `#include` directive;
+- the space between the `int` declaration and the main function;
+- the space between the `int` declaration and the `height` variable;
+- the space between `return` and `0`.
+
+Indeed, without all "unnecessary" spaces the programme would be:
+
+```c
+#include<stdio.h>
+int main(void){int height,length,width,volume,weight;height=8;length=12;width=10;volume=height*length*width;weight=(volume+165)/166;printf("Dimensions: %dx%dx%d\n",length,width,height);printf("Volume (cubic inches): %d\n",volume);printf("Dimensional weight (pounds): %d\n",weight);return 0;}
