Formula of surface area of cuboids:
Surface_area = 2 *(w*l + l*h + h*w)
Formula of volume of cuboids:
Volume = w * l * h
Space diagonal of cuboids:
Space_diagonal = √ (w*w + l*l + h*h)
C code:
#include<stdio.h>
int main(){
float w,l,h;
float surface_area,volume,space_diagonal;
printf("Enter size of width, length and height of a cuboids : ");
scanf("%f%f%f",&w,&l,&h);
surface_area = 2*(w*l + l*h + h*w);
volume = w * l * h;
space_diagonal = sqrt(w*w + l*l + h*h);
printf("Surface area of cuboids is: %.3f",surface_area);
printf("\nVolume of cuboids is : %.3f",volume);
printf("\nSpace diagonal of cuboids is : %.3f",space_diagonal);
return 0;
}
Sample output:
Enter size of width, length and height of cuboids: 5 10 4
Surface area of cuboids is: 220.000
Volume of cuboids is: 200.000
Space diagonal of cuboids is: 11.874
