tlng supaya dpt pahala!

1) Volume balok = P x L x T= 9 x 7 x 10= 630 cm²
2) Volume Balok = P x L x T= 12 x 9 x 15=1.620 cm²
3) 210 cm² = P x L x T
= 210 cm² = 6 x L x 5
= 210 cm² = 30 x L
=210 cm²÷30 = L
L = 7 cm
4)Volume Balok = P x L x T = 10 x 6 x 4 = 240 cm²
5)1.350 cm² = P x L x T
= 1.350 = 9 x 15 x T
= 1.350 = 135 x T
= 1.350÷135 = T
T = 10

semoga bermanfaaat ya sob
