Question

Diketahui balok panjangnya 9cm, lebaran 6, dan tingginya 7 berapa volume dan luas permukaan balok

Answer 1

Jawaban:

• Panjang = 9 cm
• Lebar = 6 cm
• Tinggi = 7 cm

Volume balok

[tex] \sf V = p \times l \times t[/tex]

[tex] \sf V = 9 \times 6 \times 7[/tex]

[tex] \sf V = 9 \times 42[/tex]

[tex] \sf V = \red{378 \: {cm}^{3} }[/tex]

Luas permukaan balok

[tex] \sf L = 2(pl) + (pt) + (lt)[/tex]

[tex] \sf L = 2(9 \times 6) + (9 \times 7) + (6 \times 7)[/tex]

[tex] \sf L = 2(54) + (63) + (42)[/tex]

[tex] \sf L = 2(54) + (105)[/tex]

[tex] \sf L = 2(159)[/tex]

[tex] \sf L = \red{318 \: {cm}^{2} }[/tex]

Answer 2

V = (PLT)

= (9 . (6) . (7)

= (9 . (42)

= 378 CM³

LP = 2(PL + PT + LT)

= 2(9(6) + (9(7) + (6(7)

= 2(54 + 63 + 42)

= 2(54 + 105)

= 2(159)

= 318 CM²
