Question

Формула усіх граней параллепіпеда

Answer 1

S = 2ah+2aH+2bH = 2(ah+aH+bH) или S = 2(Sa+Sb+Sc) = 2(ab+ bc+ ac), а именно, удвоенная сумма площадей граней параллелепипеда.

Answer 2

Formula for the Total Surface Area of a Parallelepiped

The formula for the total surface area of a parallelepiped is given by:

Total Surface Area = 2(ab + bc + ac)

Where: - a, b, c are the lengths of the three edges of the parallelepiped.

This formula calculates the total surface area by summing the areas of all six faces of the parallelepiped.
