Diketahui:

Panjang(p) = 10 cm

Lebar(l) = 12 cm

Tinggi(t) = 20 cm

Dijawab:

  • [tex] \colorbox{yellow}{ \sf \: Volume}[/tex]

V = p × l × t

V = 10 × 12 × 20

V = [tex] \underline{ \boxed{ \red{ \sf \: 2.400~cm³}}}[/tex]

[tex] \: \: [/tex]

  • [tex] \colorbox{yellow}{ \sf \: Luas}[/tex]

L = p × l

L = 10 × 12

L = [tex] \underline{ \boxed{ \red{ \sf \: 128~cm²}}}[/tex]

[tex] \: \: \: [/tex]

  • [tex] \colorbox{yellow}{ \sf \: Keliling}[/tex]

K = 4 × (p + l + t)

K = 4 × (10 + 12 + 20)

K = 4 × 42

K = [tex] \underline{ \boxed{ \red{ \sf \: 168~cm}}}[/tex]

[tex] \: \: [/tex]

  • [tex] \colorbox{yellow}{ \sf \: Luas~permukaan}[/tex]

Lp = 2 × (pl + pt + lt)

Lp = 2 × (10 × 12) + (10 × 20) + (12 × 20)

Lp = 2 × (120 + 200 + 240)

Lp = 2 × 560

Lp = [tex] \underline{ \boxed{ \red{ \sf \: 1.120 ~cm²}}}[/tex]
