Calculation of the Length of All Edges of a Rectangular Parallelepiped

To calculate the length of all edges of a rectangular parallelepiped, we can use the formula:

Length of an edge (D) = √(a^2 + b^2 + c^2)

Given the dimensions of the rectangular parallelepiped as follows: - a = 6 cm - b = 7 cm - c = 9 cm

Let's substitute these values into the formula:

D = √(6^2 + 7^2 + 9^2)

Calculating the values:

D = √(36 + 49 + 81) = √(166) ≈ 12.88 cm

Therefore, the length of all edges of the rectangular parallelepiped is approximately 12.88 cm.
