Question

calcule a area total e o volume de um paralelepipedo retangulo cuja as dimensoes= 2m, 3m, 6m.

Answer 1

v=a.b.c
v= 2.3.6
v=36m3

A= 2a.b + 2a.c + 2b.c
A= 2.2.3+2.2.6+2.3.6
A=72m2

Answer 2

Formula do volume:

V = a. b.c
V = 2 . 3 . 6
V = 6 . 6
V = 36 m³

===
Formula da área total:

At = 2.(ab + ac + bc)
At = 2.(2.3 + 2.6 + 3.6)
At = 2.(6 + 12 + 18)
At = 2 . (36)
At = 72 m²
