Given a rectangular parallelepiped, its length is 9 cm, width 3 cm, height 7 cm, find the sum of the lengths of all edges


a = 9 cm;

b = 3 cm;

s = 7 cm;

P =? cm.

A rectangular parallelepiped is a three-dimensional shape with rectangles on its sides. The perimeter of the parallelepiped is calculated using the following formula: P = 4 * (a + b + c) Where P is the perimeter, a, b and c are the length of the edges of the parallelepiped.

P = 4 * (a + b + c) = 4 * (9 + 3 + 5) = 4 * 18 = 72 (cm)

Answer: 72 cm is the sum of the lengths of all the edges of a rectangular parallelepiped.
