Answer 2

Finding the Lengths of the Edges of a Rectangular Parallelepiped

To find the lengths of the edges of a rectangular parallelepiped, we need to use the given information about the congruent sides of a right triangle and the volume of the parallelepiped.

Let's break down the problem step by step:

1. We are given that the sum of the lengths of the congruent sides of a right triangle is 60 cm. However, we don't have the exact lengths of the sides. Therefore, we cannot directly determine the lengths of the edges of the parallelepiped from this information.

2. We are also given that the volume of the parallelepiped is 6.24 dm³. To find the lengths of the edges, we need to use this information.

3. The volume of a rectangular parallelepiped is calculated by multiplying the lengths of its three edges. Let's assume the lengths of the edges are a, b, and c. Therefore, we have the equation:

a * b * c = 6.24 dm³.

4. Since the volume is given in cubic decimeters (dm³), we need to convert it to cubic centimeters (cm³) to match the units of the lengths of the congruent sides of the right triangle.

1 dm³ = 1000 cm³.

Therefore, 6.24 dm³ = 6.24 * 1000 cm³ = 6240 cm³.

5. Now, we have the equation:

a * b * c = 6240 cm³.

6. Unfortunately, we don't have enough information to directly solve this equation. We need additional information about the relationship between the lengths of the congruent sides of the right triangle and the lengths of the edges of the parallelepiped.

Based on the given information, it seems that there might be a missing piece of information or a typo in the question. Without further details, it is not possible to determine the lengths of the edges of the parallelepiped.

Please provide any additional information or clarify the question if possible, and I will be happy to assist you further.
