Solution
Zadatak 1.61 opisuje četverostranu piramidu , čija je baza paralelogram , s točkama definiranim vektorima: Traži se površina trokuta i volumen piramide, s danim rješenjima:
1. Površina trokuta
Površina trokuta može se izračunati koristeći vektorski produkt. Prvo definiramo vektore i .
- Vektor nije eksplicitno naveden, ali pretpostavljamo da je , jer je to točka vrha piramide. Dakle, .
Nakon toga, koristimo formulu za površinu trokuta koja je polovica normirane vrijednosti vektorskog produkta između i ( \vec{AO} \
