Answer:
// code in C++.
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
// variables
int length=10,height=7,width=5;
// find the volume of
int vol=length*height*width;
// find the surface area
int sa=2*(length*width+length*height+height*width);
// find the perimeter
int peri=4*(length+width+height);
// print the volume
cout<<"Volume is: "<<vol<<" cm^3."<<endl;
// print the surface area
cout<<"Surface area is: "<<sa<<" cm^2."<<endl;
// print the perimeter
cout<<"Perimeter is: "<<peri<<" cm."<<endl;
return 0;
}
Explanation:
Declare and initialize length=10, width=5 and height=7.calculate volume by multiply length, width and height and assign to variable "vol".Then find the surface area as 2*(length*width+length*height+height*width) and assign it to variable "sa".Then find the perimeter as 4*(length+width+height) and assign to variable "peri". Print the volume, perimeter and surface area.
Output:
Volume is: 350 cm^3.
Surface area is: 310 cm^2.
Perimeter is: 88 cm.
