Answer 1

Jawaban:

1. Luas = 248 cm²

Volume = 240 cm³

2. Luas = 392 cm²

Volume = 480 cm³

3. Luas = 198 cm²

Volume = 162 cm³

4. Luas = 470 cm²

Volume = 600 cm³

5. Luas = 1.150 cm²

Volume = 1.875 cm³

Penjelasan dengan langkah-langkah:

1. Luas = 2 × ( p.l + p.t + l.t )

= 2 × ( 10cm.6cm + 10cm.4cm + 6cm.4cm)

= 2 × ( 60 cm + 40 cm + 24 cm )

= 2 × ( 124 cm )

= 248 cm²

Volume = p × l × t

= 10 cm × 6 cm × 4 cm

= 240 cm³

2. Luas = 2 × ( p.l + p.t + l.t )

= 2 × ( 12cm.8cm + 12cm.5cm + 8cm.5cm )

= 2 × ( 96 cm + 60 cm + 40 cm )

= 2 × ( 196 cm )

= 392 cm²

Volume = p × l × t

= 12 cm × 8 cm × 5 cm

= 480 cm³

3. Luas = 2 × ( p.l + p.t + l.t )

= 2 × ( 9cm.6cm + 9cm.3cm + 6cm.3cm )

= 2× ( 54 cm + 27 cm + 18 cm )

= 2 × ( 99 cm )

= 198 cm²

Volume = p × l × t

= 9 cm × 6 cm × 3 cm

= 162 cm³

4. Luas = 2 × ( p.l + p.t + l.t )

= 2 × ( 15cm.8cm + 15cm.5cm + 8cm.5cm )

= 2 × ( 120 cm + 75 cm + 40 cm )

= 2 × ( 235 cm )

= 470 cm²

Volume = p × l × t

= 15 cm × 8 cm × 5 cm

= 600 cm³

5. Luas = 2 × ( p.l + p.t + l.t )

= 2 × ( 25cm.15cm + 25cm.5cm +

15cm.5cm )

= 2 × ( 375 cm + 125 cm + 75 cm )

= 2 × ( 575 cm )

= 1.150 cm²

Volume = p × l × t

= 25 cm × 15 cm × 5 cm

= 1.875 cm³
