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

Given:
The first edge of a rectangular parallelepiped is 3 cm.
The length of the second edge of the parallelepiped is 4 cm.
The length of the third edge of the figure is 5 cm.

Find the area of the first face of the rectangular parallelepiped:
3 * 4 = 12 cm2.
Let’s calculate the area of the second face of the parallelepiped:
3 * 5 = 15 cm2.
Let’s find the area of the third facet of the figure:
4 * 5 = 20 cm2.
Let’s calculate the sum of the areas of all faces of a rectangular parallelepiped:
12 * 2 + 15 * 2 + 20 * 2 = 24 + 30 + 40 = 94 cm2.
Answer: 94 cm2.
