Math Problem Statement
Solution
The problem in the image asks the following:
"Знайдіть площу повної поверхні прямокутного паралелепіпеда, якщо його діагональ більша за ребра паралелепіпеда на 10 см, 9 см і 1 см відповідно."
Translated to English:
"Find the total surface area of a rectangular parallelepiped if its diagonal is larger than the edges of the parallelepiped by 10 cm, 9 cm, and 1 cm, respectively."
Let's solve the problem step by step:
Step 1: Define the dimensions
Let the edges of the rectangular parallelepiped be , , and . From the problem, we know the following relationships between the diagonal and the edges:
where is the diagonal of the parallelepiped.
Step 2: Diagonal formula
The diagonal of a rectangular parallelepiped is given by the formula:
Step 3: Use the relationships between the edges and the diagonal
From the relationships in Step 1, we can express , , and in terms of :
Step 4: Substitute into the diagonal formula
