Consider the following statements: int num1, num2, num3; double length, width, height; double volume; num1 = 6; num2 = 7; num3 = 4; length = 6.2; width = 2.3; height = 3.4 and the function prototype: double box(double, double, double); Which of the following statements are valid or invalid? a. volume = box(length, width, height); b. volume = box(length, 3.8, height); c. cout << box(num1, num3, num2) << endl; d. cout << box(length, width, 7.0) << endl; e. volume = box(length, num1, height); f. cout << box(6.2, , height) << endl; g. volume = box(length + width, height); h. volume = box(num1, num2 + num3);

int num1, num2, num3;

double length, width, height;

double volume;

num1 = 6;
num2 = 7;
num3 = 4;


length = 6.2;
width = 2.3;
height = 3.4 and the function prototype: 


double box(double, double, double);


Which of the following statements are valid or invalid?
a. volume = box(length, width, height);			--> VALID
b. volume = box(length, 3.8, height);			--> VALID
c. cout << box(num1, num3, num2) << endl;		--> VALID
d. cout << box(length, width, 7.0) << endl;		--> VALID
e. volume = box(length, num1, height);			--> Valid
f. cout << box(6.2, , height) << endl;			--> Invalid as the function double box(double, double, double) requires 3 arguments to be passed
g. volume = box(length + width, height);		--> Invalid as the function double box(double, double, double) requires 3 arguments to be passed
h. volume = box(num1, num2 + num3);				--> Invalid as the function double box(double, double, double) requires 3 arguments to be passed
