The dimensions of a rectangular parallelepiped are 9: 13: 7. Find the sum of the edges of a rectangular parallelepiped if the length of the smaller edge is 18 centimeters.

If the length of the smaller edge of the rectangular parallelepiped is 18 centimeters and the measurements of the rectangular parallelepiped are 9: 13: 7, then the smallest edge is 7 parts. Let’s find how much is in one part, for this 18: 7 = 18/7. Then one of the dimensions of a rectangular parallelepiped will be 9 * 18/7 = 162/7 = 23 whole 1/7 (see), the second 18/7 * 13 = 234/7 = 33 whole 3/7 (see). So, to find the sum of the edges of a rectangular parallelepiped, you need to add its three dimensions and multiply by 4 and get: (23 integers 1/7 + 33 integers 3/7 + 18) * 4 = (56 integers 4/7 + 18) * 4 = 74 points 4/7 * 4 = 298 points 2/7 (see).
Answer: 298 whole 2/7 cm.
