Penjelasan dengan langkah-langkah:

1.

Dik.

a.

P = 6 kubus

l = 4 kubus

t = 3 kubus

V = p × l × t

V = 6 × 4 × 3

V = 72 kubus atau dalam bentuk satuan panjang (72 cm³)

b,

P = 10 kubus

l = 6 kubus

t = 4 kubus

V = p × l × t

V = 10 × 6 × 4

V = 240 kubus atau 240 cm³

2.

a.

p = 7 cm

l = 3 cm

t = 5 cm

V = 7 × 3 × 5

V = 105 cm³

b.

p = 12 cm

l = 4 cm

t = 6 cm

V = 12 × 4 × 6

V = 288 cm³

3. Volume Balok 1 + Volume Balok 2

= (p1 × l1 × t1)+ (p2 × l2 × t2)

= (32 × 15 × 8) + (20 × 15 × 10)

= 3.840 cm³ + 3.000 cm³

= 6.840 cm³

4.

= (90 × 100 × 40) + (30 × 100 × 50)

= (360.000) + (150.000)

= 510.000 cm³

Sekian, semoga membantu (*ﾟ▽ﾟ)ﾉ
