How the Calculator Works

To use the calculator, input the lengths of the three sides of the triangular base (labeled as Side A, Side B, and Side C) and the height of the prism. The calculator uses these inputs to compute the total surface area, which includes both the lateral surface area and the area of the two triangular bases.

Understanding the Formula

The calculator employs a combination of mathematical formulas. For the triangular base, Heron’s formula is used:

Area = square root (s * (s – a) * (s – b) * (s – c))

where s is the semi-perimeter of the triangle (s = (a + b + c) / 2). The height of the base is derived from this area. The total surface area is then calculated by adding the lateral area (perimeter of the base times the height of the prism) to twice the area of the base.
