Formula

surface area = base^2 + 2 x base x slant height

Add the square base area to the four triangular faces combined.

This version uses slant height for the side triangles.

Example

8 units, 7 units gives Surface Area 176.

Check

Mixing units or scales across base side length, slant height before calculating surface area.
Rounding too early when the surface area still feeds another step.
