A rectangular parallelepiped is a parallelepiped with each face represented by a rectangle.
Its surface area (sum of areas) is calculated by the formula:
S = 2 * (ab + bc + ac). Let’s find its value for such a figure, the dimensions of which are 8, 6 and 12 m:
S = 2 * (8 * 6 + 6 * 12 + 8 * 12) = 2 * (48 + 72 + 96) = 2 * 216 = 432 m².
