Question

Calcula el área total del paralelepípedo que aparece en la imagen,

Answer 1

Respuesta:

            [tex]432cm^{2}[/tex]

Explicación paso a paso:

[tex]Largo: L = 8cm[/tex]

[tex]Ancho: a = 2cm[/tex]

[tex]Altura: h = 20cm[/tex]

[tex]Area-total: At = ?[/tex]

[tex]At = 2(L*h)+2(a*h)+2(a*L)[/tex]

[tex]At = 2 ( 8cm*20cm)+2(2cm*20cm)+2(2cm*8cm)[/tex]

[tex]At = 2(160cm^{2} )+2(40cm^{2} )+2(16cm^{2})[/tex]

[tex]At = 320cm^{2} +80cm^{2} +32cm^{2}[/tex]

[tex]Luego: At = 432cm^{2}[/tex]
