The sum of the lengths of all the edges of a rectangular parallelepiped is 116 cm, and its two dimensions are 12 cm, 11 cm. Find the third dimension of the parallelepiped.
In total, there are 12 edges in a rectangular parallelepiped, there are 4 edges for each dimension.
We calculate the length of the edges of known measurements:
12 * 4 + 11 * 4 = 92 (cm)
Let’s find the length of the third dimension:
(116 – 92) / 4 = 6 (cm)
