Penjelasan dengan langkah-langkah:

SOAL NO. 5

V Kubus = s × s ×

V Kubus = 5 × 5 × 5

V Kubus = 125cm³

V Balok = p × l × t

V Balok = 14 × 9 × 18

V Balok = 2.268cm³

Gabungan = 125 + 2.268

= 2.393cm³

SOAL NO. 6

10 = 2 × 5

15 = 3 × 5

25 = 5^2

kpk = 2 × 3 × 5^2 = 6 × 25 = 150.

SOAL NO. 7

V Tabung = π × r × r × t

V Tabung = ²²/7 × 25 × 25 × 21

V Tabung = ²²/7 × 625 × 21

V Tabung = 41.250cm3

SOAL NO. 8

V Balok = p × l × t

V Balok = 7 × 5 × 11

V Balok = 385cm³

V Segitiga = ((a × t) ÷ 2) × t.p

V Segitiga = ((7 × 5) ÷ 2) × 11

V Segitiga = 192,5cm³

Gabungan = 385 + 192,5

= 577,5cm³

SOAL NO. 9

⅓ × L.a × t

= ⅓ × (½ × D1 × D2) × t

= ⅓ × (½ × 10 × 10 ) × 9

= ⅓ × (50) × 9

= ⅓ × 450

= 150Cm³
