Answer 1

PARALELEPÍPEDO

V = a.b.c

V = 12.3.5

V = 180 cm

CONE

V = π.r².h / 3

V = 3,14.4².10 / 3

V = 3,14.16.10 / 3

V = 502,4 /  3

V = 167,46 cm³

CUBO

V = a²

V = 5²

V = 25 cm³

CILINDRO

V = π.r².h

V = 3,14.3².3

V = 3,14.9.3

V = 84,78 cm³

Tronco do cone

V = π.h/3 (R² + Rr + r²)

V = 3,14.3/3.(3²+3.2+2²)

V = 9,42/3.(9+6+4)

V = 3,14.19

V = 59,6 cm³

Esfera

V = 4/3.πr³

V = 1,3.3,14.8            8 ← 2³

V = 32,6 cm³
