Penjelasan dengan langkah-langkah:

No. 24)

Volume Balok

V = p × l × t

V = 25 × 8 × 10

V = 2.000cm³

Volume Limas

V = ⅓ × L.a × t

V = ⅓ × 25 × 10

V = ⅓ × 250

V = 83cm³

Gabungan = 2.000 + 83

Gabungan = 2.083cm³

No. 25)

Volume Tabung

V = π × r × r × t

V = 22/7 × (14 × 14) × 12

V = 22/7 × (196) × 12

V = 22/7 × 2.352

V = 7.392cm³

Volume Kerucut

V = ⅓ × π × r × r × t

V = ⅓ × 22/7 × (14 × 14) × 12

V = ⅓ × 22/7 × (196) × 12

V = ⅓ × 22/7 × 2.352

V = 2.464cm³

Gabungan = 7.392 + 2.464

Gabungan = 9.856cm³

No. 26)

Luas Permukaan Kubus

Lp = 6 × s × s

Lp = 6 × 10 × 10

Lp = 6 × 100

Lp = 600cm²

Luas Permukaan Balok

Lp = 2 × (p × l) + (p × t) + (l × t)

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

Lp = 2 × (240) + (200) + (120)

Lp = 2 × (440) + (120)

Lp = 2 × (560)

Lp = 1.120cm²

Gabungan = 600 + 1.120

Gabungan = 1.720cm²
