tolong dicari buat caranya

1.) V = La×ts
= 1/2×a×ta×ts
= 1/2×6cm×11cm×8cm
= 1/2×66cm×8cm
= 33cm² × 8cm = 264cm³
*ta= tinggi alas, ts= tinggi segitiga

2.) V = La×ts
= 1/2×a×ta×ts
= 1/2×12dm×15dm×31dm
= 1/2×180dm×31dm
= 90dm² × 31dm = 1890dm³

3.) V = La×ts
= 1/2×a×ta×ts
= 1/2×3m×6m×12m
= 1/2×18m×12m
= 9m² × 12m = 108m³

4.) V = La×ts
= 1/2×a×ta×ts
= 1/2×14mm×27mm×33mm
= 1/2×378mm×33mm
= 189mm² × 33mm = 6237mm³

5.) V = La×ts
= 1/2×a×ta×ts
= 1/2×38dm×35dm×47dm
= 1/2×1330dm×47dm
= 665dm²×47dm = 31.255dm³


semoga bermanfaat ya! :)
