Pp = 4² = 16
h=4√6
Pb=2*4*4√6=32√6
Pc=16+32√6
V = ⅓ * Pp * H
H² + (4√3)² = 10²
H² = 100 - 48
H = 2√13
V = ⅓ * 16 * 2√13 = 10⅔√13
2. V = 50√3
⅓ * Pp * 5√3 = 50√3 |*3
Pp * 5√3 = 150√3 |:5√3
Pp = 30
a² = 30
a = √30
3. I) a = 12
x = 24
y = 3√3
II) a = 6
k = 10
H² + a² = k²
H² = 100 - 36
H = 8
III) H = 8
k = 12
H² + (½x)² = k²
(½x)² = 144 - 64 = 80
½x = 4√5
x = 8√5
a=4
l=10
Pp=a²
Pp=4²=16
d=a√2
d=4√2
H²=l²-(d/2)²
H²=10²-(2√2)²
H²=100-8
H=√92=√(4*13)=2√13
V=⅓PpH
V=⅓ *16*2√13
V=(32√13)/3
h²=l²-(a/2)²
h²=100-4=96
h=√96=√(16*6)=4√6
Pb=4*[(ah)/2]=2ah
Pb=2*4*4√6=32√6
Pc=Pp+Pb
Pc=16+32√6
zad.2.
H=5√3
V=50√3
a=?
V=⅓PpH /*3
3V=PpH
Pp=3V/H
Pp=(3*50√3)/5√3
Pp=30
Pp=a²
a=√Pp
a=√30
zad.3.Nie wiem o co chodzi!Więcej szczegółów.
