Jawaban:

3) LP = 6 × S²

= 6 × 10 × 10

= 600 cm²

V = S × S × S

V = 10 × 10 × 10

V = 1.000 cm³

4) LP = 2 × (P×L) + (P×t) + (L×t)

= 2 × (15×10) + (15×13) + (10×13)

= 2 × 150 + 195 + 130

= 300 + 195 + 130

= 495 + 130

= 625 cm³

V = P × L × t

V = 15 × 10 × 13

V = 1.950 cm³

5) LP = 2 × (P×L) + (P×t) + (L×t)

= 2 × (17×7) + (17×13) + (7×13)

= 2 × 119 + 221 + 91

= 238 + 221 + 91

= 459 + 91

= 550 dm²

V = P × L × t

V = 17 × 7 × 13

V = 1.547 dm³

6) LP = 6 × S²

= 6 × 12 × 12

= 864 cm²

V = S × S × S

V = 12 × 12 × 12

V = 1.728 cm³

7) LP = 2 × (P×L) + (P×t) + (L×t)

= 2 × (13×4) + (13×8) + (4×8)

= 2 × 52 + 104 + 32

= 104 + 104 + 32

= 208 + 32

= 240 cm²

V = P × L × t

V = 13 × 4 × 8

V = 416 cm³

8) LP = 2 × (P×L) + (P×t) + (L×t)

= 2 × (19×12) + (19×15) + (12×15)

= 2 × 228 + 285 + 180

= 456 + 285 + 180

= 741 + 180

= 921 dm²

V = P × L × t

V = 19 × 12 × 15

V = 3.420 dm³
