Answer 2

Calculation of the lateral surface area of a rectangular parallelepiped

To calculate the lateral surface area of a rectangular parallelepiped, we need to find the sum of the areas of all its lateral faces.

The given dimensions of the rectangular parallelepiped are: - Length: 1 cm - Width: 2 cm - Height: 3 cm

To calculate the lateral surface area, we need to find the areas of the four lateral faces. The formula to calculate the area of a rectangle is A = l * w, where A is the area, l is the length, and w is the width.

Let's calculate the area of each lateral face and then sum them up to find the total lateral surface area.

1. Area of the first lateral face: - Length = 1 cm - Width = 3 cm - Area = 1 cm * 3 cm = 3 cm²

2. Area of the second lateral face: - Length = 2 cm - Width = 3 cm - Area = 2 cm * 3 cm = 6 cm²

3. Area of the third lateral face: - Length = 1 cm - Width = 3 cm - Area = 1 cm * 3 cm = 3 cm²

4. Area of the fourth lateral face: - Length = 2 cm - Width = 3 cm - Area = 2 cm * 3 cm = 6 cm²

Now, let's sum up the areas of all the lateral faces: 3 cm² + 6 cm² + 3 cm² + 6 cm² = 18 cm²

Therefore, the lateral surface area of the given rectangular parallelepiped with dimensions 1 cm, 2 cm, and 3 cm is 18 cm².
