Plis jawab besok mau di kumpul
Jawaban:
1. – Luas alas balok = p x l = 7 x 4 = 28 cm²
– volume blok = p x l x t = 7 x 4 x 3 = 84cm
2. – Luas alas balok = 10 x 6 = 60 cm²
– volume balok = 10 x 6 x 2 = 120 cm³
3. – Luas alas balok = 12 x 8 = 96 cm²
– volume balok = 12 x 8 x 4 = 402 cm³
4. – Luas alas balok = 9 x 5 = 45 dm²
– volume balok = p x l x t
90 = 9 x 5 x t
90 = 45 t
t = 90/45
t = 2 dm
5. – Luas alas balok = 8 x 5 = 40 dm²
– volume balok = p x l x t
240 = 8 x 5 x t
240 = 40 t
t = 240/40
t = 6 dm
6. – volume balok = p x l x t
540 = 18 x l x 3
540 = 54 l
l = 540/54
l = 10 dm
– luas alas balok = p x l = 18 x 10 = 180dm²
7. – luas alas balok = p x l
60 = 12 x l
l = 60/12
l = 5 m
– volume balok = 12 x 5 x 4 = 240 m³
8. – luas alas balok = p x l
120 = 16 x l
l = 120/16
l = 7,5 m
– volume balok = 16 x 7,5 x 5 = 600 m³
9. – volume balok = p x l x t
960 = p x 8 x 10
960 = 80 p
p = 960/80
p = 12 m
– luas alas balok = 12 x 8 = 96 m²
10. – volume balok = p x l x t
720 = p x 6 x 8
720 = 48 p
p = 720/48
p = 15 m
– luas alas balok = 15 x 6 = 90 m²
