Question

cauculu o volume e a rea total do paralepido a seguir 8cm 10cm 20cm

Answer 1

a = 8 cm  b = 10 cm  c = 20 cm

===
Área total do paralelepípedo

At = 2 . (ab + ac + bc)
At = 2 . (8.10 + 8.20 + 10.20)
At = 2 . (80 + 160 + 200)
At = 2 . (440)
At = 880 cm²

===Volume do paralelepípedo

V = a.b.c
V = 8 . 10 . 20
V = 8 . 200
V = 1600 cm³
