The length of the rectangular parallelepiped is 4 cm, the width is 3 cm, and the height is 2 cm.

The length of the rectangular parallelepiped is 4 cm, the width is 3 cm, and the height is 2 cm. Find the area of each face of the parallelepiped. Find the sum of the areas of all faces (total surface area).

S1 = a * b = 4 * 3 = 12 cm ^ 2;
S2 = b * c = 3 * 2 = 6 cm ^ 2;
S3 = a * c = 4 * 2 = 8 cm ^ 2;
To find the total surface area, you need to add all the areas and multiply the result by 2, since in the parallelepiped the parallel faces are equal:
S total = 2 * (S1 + S2 + S3) = 2 * (12 + 6 + 8) = 2 * 26 = 52 cm ^ 2.
Answer: 52cm ^ 2.
