Given a rectangular parallelepiped with measurements 1cm, 2cm, 3cm. Calculate the side area

Given a rectangular parallelepiped with measurements 1cm, 2cm, 3cm. Calculate the side area of a rectangular parallelepiped.

1. Let a = 3 cm – the length of the base of the rectangular parallelepiped, b = 2 cm – the width of the base, h = 1 cm – the height;
2. Then the area of the lateral surface of a rectangular parallelepiped is calculated by the formula:
S = 2 * (a * b + a * h + b * h) = 2 * (3 * 2 + 3 * 1 + 2 * 1) = 2 * (6 + 3 + 2) = 22 cm ^ 2;
3. Answer: S = 22 cm ^ 2.
