V= ⅓a²*H
260= (ah)/2
h=52
obliczenie H:
(5√2)²+H²= 52²
50+H²=2704
H²= 2754
H= √2754
V= ⅓*10²*√2754
V= 100/3 √2754
Pb = 260 cm²
V = ?
H = ?
Pb = 260 : 4 = 65
Pt = ½ * a * h
65 = ½ * 10 * h | : ½
130 = 10 * h | : 10
h = 13 cm
a√2 = przekątna kwadratu
10√2
½ * 10√2 = 5√2 = a
c = 13
a² + b² = c²
27 + b² = 169 | - 27
b² = 169 - 27 = 142
b = √142 = H
Pp = 10² = 100 cm²
V = ⅓ Pp * H
V = √⅓ * √100 * √142
V = 33,(3) * √142
V = 1609,(3) cm³
[Coś taki jakiś niezwyczajny wynik więc nie mam pewności czy to dobrze.]
