The edges of a rectangular parallelepiped are 3 cm 4 cm and 5 cm Find the total surface area of a rectangle on a parallelepiped.

The total surface area of a rectangular parallelepiped is equal to twice the sum of the areas of its three faces.

Thus, we find the area of the total surface of a rectangular parallelepiped, the edges of which are 3 cm, 4 cm and 5 cm:

S = 2 (3 * 4 + 4 * 5 + 3 * 5) = 2 (12 + 20 + 15) = 2 * 47 = 94 (cm²).

Answer: the total surface area of a rectangular parallelepiped is 94 cm².
