1. ½×(a+b) ×t
= ½ × (15+(15-3)) × 16
= 27 × 8 = 216 cm²

4. ½ × d1×d2
= ½ × 43 × 52
= 43 × 26
= 1.118 cm²

2.½×(a+b) ×t
= ½×(18+25)×14
= 43 × 7
= 301 cm²

3. ½×d1×d2
= ½×51×38
= 51×19
= 969 cm²

5. L = 476 cm²
T = 476/2 : (20+36)
= 238 : 56
= 4,25 cm
6. V. K = r³= 17³ = 4.913 cm³
V. B = la×t = 580×8 = 4.640 cm³
Selisih = 4.913-4.640 = 273 cm³

7. V = 15×4×3 = 180 cm³
V kardus = 180 × 1.200 = 216.000 cm³
R kardus = ³√216.000 = 60 cm

8. V = p×l×t
= 12×7×9
= 756 cm³

9.V = p×l×t
= 20×8×12
= 1.920 cm³

10.
7 m = 70 dm
4 m = 40 dm
0,75 m = 7,5 dm

V = p×l×t
= 70×40×7,5
= 21.000 dm³ = 21.000 liter
