Determine a right parallelepiped with minimal area, if its volume is strictly greater than $1000$, and the lengths of it sides are integer numbers.
1. **Define the problem and constraints:**
   We need to find a right parallelepiped (rectangular box) with integer side lengths \(a\), \(b\), and \(c\) such that its volume \(V = abc\) is strictly greater than 1000, and its surface area \(A\) is minimized. The surface area \(A\) of a right parallelepiped is given by:
   \[
   A = 2(ab + bc + ca)
   \]
   We need to minimize \(A\) under the constraint \(abc > 1000\).

2. **Initial assumption and simplification:**
   Without loss of generality, assume \(a \leq b \leq c\). This helps in reducing the number of cases to check.

3. **Volume constraint:**
   Since \(abc > 1000\), we start by checking the smallest possible values for \(a\) and then find corresponding \(b\) and \(c\) that satisfy the volume constraint and minimize the surface area.

4. **Case \(a = 10\):**
   \[
   a = 10 \implies bc > \frac{1000}{10} = 100
   \]
   Let's check \(b = 10\) and \(c = 11\):
   \[
   V = 10 \times 10 \times 11 = 1100 \quad (\text{which satisfies } V > 1000)
   \]
   \[
   A = 2(10 \times 10 + 10 \times 11 + 11 \times 10) = 2(100 + 110 + 110) = 2 \times 320 = 640
   \]
   Half area:
   \[
   A_2 = \frac{A}{2} = 320
   \]

5. **Check smaller values of \(a\):**
   If \(a \leq 3\), then:
   \[
   bc \geq \frac{1001}{a}
   \]
   This would make \(bc\) very large, and it is unlikely to minimize the surface area. Therefore, we check values \(a \in \{4, 5, 6, 7, 8, 9, 10\}\).

6. **Check \(a = 7\):**
   \[
   a = 7 \implies bc > \frac{1000}{7} \approx 143
   \]
   Let's check \(b = 12\) and \(c = 12\):
   \[
   V = 7 \times 12 \times 12 = 1008 \quad (\text{which satisfies } V > 1000)
   \]
   \[
   A = 2(7 \times 12 + 12 \times 12 + 12 \times 7) = 2(84 + 144 + 84) = 2 \times 312 = 624
   \]
   Half area:
   \[
   A_2 = \frac{A}{2} = 312
   \]

7. **Compare the results:**
   For \(a = 10, b = 10, c = 11\), the half area \(A_2 = 320\).
   For \(a = 7, b = 12, c = 12\), the half area \(A_2 = 312\).

   The configuration \((a, b, c) = (7, 12, 12)\) gives a smaller surface area.

Conclusion:
The right parallelepiped with minimal area, given the volume constraint, has side lengths \(a = 7\), \(b = 12\), and \(c = 12\).

The final answer is \( \boxed{ (a, b, c) = (7, 12, 12) } \)
