Question

qual o volume de uma piramide d base hexagonal com 50cm de altura e 20cm d aresta da base​

Answer 1

Resposta:

Area do hexagono:

A = $\frac{3*20^{2}*\sqrt{3}}{2}$

A = $600\sqrt{3}$

Logo:

V = $\frac{1}{3}*600\sqrt{3}*50$

V = 10000$\sqrt{3}$ cm³

Answer 2

v = 3.a².√3/2. h/3

v = 3.20².√3/2. 50/3

v = 1200√3/2. 50/3

v = 600√3. 50/3

v = 200√3. 50

v = 10000√3 cm³
