Euler:

F + V = A + 2

A = n . F /2

Prismas:

-Regulares

V = Ab . h

-Paralelepípedo

d² = a² + b²

D² = a² + b² + c²

A = 2 . (a.b + a.c + b.c)

V = a . b . c

-Cubo

d = a 2

D = a 3

A = 6 . a²

V = a³

obs.:

-Área

T-- A = (l² . √3 )/4

H-- A = (3 . l² . √ 3)/2

Q-- A = l²

-Apótema

T-- m = (l .√3)/6

H-- m = (l . √3)/2

Q-- m = l /2

Pirâmides:

g² = h² + m²

al² = g² + (ab/2)²

V= (Ab . h )/3

Cilindros:

Ab = π . r²

At = 2 . π . r . h + 2 . π . r²

V = π . r² . h
