Tolong Dong Pakai Cara☹​

Answer 1

Jawaban:

Nomor 14:

Panjang Balok

= Volume ÷ (lebar × tinggi)

= 5.698 cm³ ÷ (11 cm × 14 cm)

= 5.698 cm³ ÷ 154 cm²

= 37 cm

Nomor 15:

Nomor 4

Nomor 16:

Luas Permukaan Kubus

= 6 × (sisi × sisi)

= 6 × (9 cm × 9 cm)

= 6 × 81 cm²

= 486 cm²

Nomor 17:

Luas Permukaan Balok

= 2 + (p × l) + (p × t) + (l × t)

= 2 + (6 × 3) + (6 × 4) + (3 × 4)

= 2 + (18 cm²) + (24 cm²) + (12 cm²)

= 2 + 54 cm²

= 56 cm²

Nomor 18:

480 liter = 480 dm³

Tinggi Balok

= Volume ÷ (panjang × lebar)

= 480 dm³ ÷ (10 dm × 8 dm)

= 480 dm³ ÷ 80 dm³

= 6 cm

Nomor 19:

Volume Kubus

= sisi × sisi × sisi

= 12 dm × 12 dm × 12 dm

= 1.728 dm³

= 1.728 liter

Nomor 20:

Volume Balok

= panjang × lebar × tinggi

= 80 cm × 10 cm × 20 cm

= 16.000 cm³

= 16 dm³
