GEOMETRIA ESPACIAL
PARALELEPÍPEDO
FORMULAS:
AT=2(ab+ac+bc)
AL=2(ac+bc)
V=a.b.c
D=√b²+c²/D=√a²+c²/D²=√a²+b²+c²
A=a.c
CUBO
a/b/c=aresta
FORMULAS:
AT = 6 . a²
AB = a²
AL = 4 . a²
D = a√3 do cubo
D = a√2 da face
PRISMA
TRIANGULAR
FORMULA:
AT=sl+2sb
Al=n.a
V=Ab.h
PENTAGONAL
HEXAGONAL
N=numero de lados
A=face lateral
SL=soma das áreas das faces lateras
2Sb=soma das áreas das bases
H=altura
CILINDRO
π: é o número pi (3,14)
r: é o raio da base;
h: é a altura do cilindro
FORMULA:
AL = 2 . π . r . h
AB = π . r²
AT= 2 . π . r . (h + r)
V=AB.H
PIRAMIDE
AB=a²
AF=B.H/2
AL= (n).l.ap/2
AT= AL. AB
(AP)²=a².b²
V= AB.H/3
N=numero de lados
AP=apótema
TRIANGULO EQUILATERO:
FORMULA:
A= L².√3/4
ESFERA
FORMULAS:
A=4.π.r²
V=π.r³/3
CONE
G=geratriz
FORMULA:
AB=π.r²
AL=π.r.g
AT=π.r (g+r)
V=π.r².h/3
RELAÇÃO DE EULER:
V=vertice
F=faces
A=aresta
FORMULAS:
Só para polígonos convexos
V+F=A+2
2A=3f3+4f4+5f5+...
F3= faces triangulares/ F4= faces quadrangulares
