Answer 1

➪ Bangun ruang

• Kubus

V = Sisi×Sisi×Sisi

= 10 × 10 × 10

= 1000 cm³

Lp = Sisi × Sisi × 6

= 10 × 10 × 6

= 600 cm²

• Balok

V = panjang × lebar × tinggi

= 6 × 3 × 4

= 18 × 4

= 72 cm³

Lp = 2(p × ℓ + p × t + ℓ × t)

= 2 { (6×3) + (6×4) + (3×4) }

= 2 ( 18 + 24 + 12 )

= 2 × 54

= 108 cm²

Answer 2

  ᤷ ៶ ៸

keterangan :

Lp kubus = 6 × s²

Lp balok = 2 × ( p × l) + ( p × t ) + ( l× t)

==============================>

➩ Penyelesaian soal

A. Lp kubus = 6 × s × s

= 6 × 10 × 10

= 6×100 cm

= 600 cm²

B. Lp balok = 2 × ( p×l) + ( p × t ) + ( l×t)

= 2 × ( 6 × 3) + ( 6 × 4 ) + ( 3 × 4 )

= 2 × 18 + 24 + 12

= 2 × 54

= 108 cm²
