Odpowiedź:
a)
a = 2
h = 2
Pp = a²√3/4
V = 1/3 * a²√3/4 * 2 = a²√3/6 = 2²√3/6 = 4√3/6 = 2√3/3
b)
a = 1
h = 3
Pp = a²
V = 1/3 * a² * h = 1/3 * 1² * 3 = 1
c)
a = 2
h = 1
Pp = a²
V = 1/3 * a² * h = 1/3 * 2² * 1 = 1/3 * 4 * 1 = 4/3 = 1 1/3
d)
a = 0,5
h = √3
Pp = 3a²√3/2
V = 1/3 * 3a²√3/2 * √3 = 1/3 * 3 * 0,5² * √3 * √3/2 = 1 * 0,25 * 3/2 =
= 0,75/2 = 0,375
