| The area of a rectangular parallelepiped consists of 6 faces, which are rectangles. The area of the rectangle is

S = ab, where a and b are the sides of the rectangle.

All opposite faces of the parallelepiped are equal in pairs. The dimensions of the faces of this parallelepiped are: 6 × 8 cm, 8 × 4 cm and 6 × 4 cm. Knowing all this, we can find the total surface area of a rectangular parallelepiped. Let’s calculate it:

Spp = 2 * (6 * 8 + 8 * 4 + 6 * 4) 2 * (48 + 32 + 24) = 2 * 104 = 208 cm².

Answer: the total surface area of a rectangular parallelepiped is 208 cm².
