Answer 1

Jawaban:

1. 864 cm²

2. 1350 cm²

3. 15 cm

4. 10 cm

Penjelasan dengan langkah-langkah:

Luas permukasn kubus = 6 × s²

1. LPK = 6 × 12²

= 6 × 144

= 864 cm²

2. LPK = 6 × 15²

= 6 × 225

= 1350 cm²

3. 1350 = 6 × s²

1350/6 = s²

225 = s²

√225 = s

√225 = 15 × 15 = s

s = 15 cm

4. 600 = 6 × s²

600/6 = s²

100 = s²

√100 = s

√100 = 10 × 10 = s

s = 10 cm
