Solve the programming task below in a Python markdown code block.
This semester, Chef took X courses. Each course has Y units and each unit has Z chapters in it.

Find the total number of chapters Chef has to study this semester.

------ Input Format ------ 

- The first line will contain T, the number of test cases. Then the test cases follow.
- Each test case consists of a single line of input, containing three space-separated integers X, Y, and Z.

------ Output Format ------ 

For each test case, output in a single line the total number of chapters Chef has to study this semester.

------ Constraints ------ 

$1 ≤ T ≤ 1000$
$1 ≤ X, Y, Z ≤ 1000$

----- Sample Input 1 ------

Test case $1$: There is only $1$ course with $1$ unit. The unit has $1$ chapter. Thus, the total number of chapters is $1$.

Test case $2$: There are $2$ courses with $1$ unit each. Thus, there are $2$ units. Each unit has $2$ chapters. Thus, the total number of chapters is $4$.

Test case $3$: There is only $1$ course with $2$ units. Each unit has $3$ chapters. Thus, the total number of chapters is $6$.
