tolong jawabkanka yg benar

1. 120 x 24 = 2.880 dm³
2. 16 x 12 : 2 x 42 = 4.032cm³
3. 2.688 : 28 = 96cm²
4. 10.800 : 270 = 40cm²
5. 15 x 36 : 2 x 48 = 12.960cm³

1 . volume = luas alas × tinggi
= 120 dm2 × 24 dm=2880 dm3
2. luas alas = 1/2 × 16 cm × 12 cm
= 96 cm2
volume. = La × t = 96 cm2 × 42 cm
= 4032 cm3
3 . La = volume : tinggi
= 2688 cm3 : 28 cm = 96 cm2
4 . tinggi = volume : La
= 10800 cm3 : 270 cm2 = 40 cm
5 . La = 1/2 × 15 × 36 = 270 cm2
volume = La × t = 270 cm2 × 48 cm
= 12960 cm3

* smg membantu n maaf klo slh
