Do you mean the square base has side length 3 and the pyramid's vertical height is 8? If so:
1. Base area = 3^2 = 9.
2. Slant height l = sqrt((3/2)^2 + 8^2) = sqrt(2.25 + 64) = sqrt(66.25) = (sqrt(265))/2.
3. Lateral area = 4 × (1/2 × base × slant) = 4 × (1/2 × 3 × l) = 6l = 3·sqrt(265).
4. Total surface area = base + lateral = 9 + 3·sqrt(265) ≈ 57.84 (square units).
If you meant something else by “bases being three,” tell me what that refers to and I’ll recalculate.
