2)Alateral = 4 (area del triangulo) A lateral = 4 (24 * 40 / 2) = 1920cm2 A base = 24 * 24 = 576cm2

Atotal = A lateral + Abase = 1920 + 576 = 2496cm2

3)por el teorema de Euler

C + V = A + 2

Para toda pirámide se cumple que C = V = 15 + 1 = 16 (incluyo la base)

16 + 16 = A + 2 32 = A + 2.

A = 30

4)Alateral = 4 (area del triangulo) Alateral = 4 (5 * 8 / 2) = 80cm2 A base = 5 * 5 = 25cm2

Atotal = A lateral + Abase = 80 + 25 = 105cm2.
