Getting a head start on my classes' textbook

#include <stdio.h>

int main(void){
int height, length, width, volume, weight;

scanf("%d", &height);

volume = height * length * width;
weight = (volume + INCHES_PER_POUND - 1) / INCHES_PER_POUND;

printf("Dimensions: %dx%dx%d\n", height, length, width);
printf("Volume (cubic inches): %d\n", volume);
printf("Dimensional weight (pounds): %d\n", weight);

return 0;
