C Programming Code Examples C > Mathematics Code Examples Program to Find the Volume and Surface Area of Cuboids Program to Find the Volume and Surface Area of Cuboids This C Program calculates the volume and surface area of cuboids. The formula used in this program are surfacerea= 2(w * l + l * h + h * w) where w is width, l is length and h is height of the cuboids. volume = width * length * height. #include <stdio.h> #include <math.h> int main() { float width, length, height; float surfacearea, volume, space_diagonal; printf("Enter value of width, length & height of the cuboids:\n"); scanf("%f%f%f", &width, &length, &height); surfacearea = 2 *(width * length + length * height + height * width); volume = width * length * height; space_diagonal = sqrt(width * width + length * length + height * height); printf("Surface area of cuboids is: %.3f", surfacearea); printf("\n Volume of cuboids is : %.3f", volume); printf("\n Space diagonal of cuboids is : %.3f", space_diagonal); return 0; }
