21) 0,25:(2,5×0,025) = 0,25:0,0625 = 4 m
22) (40×25×15):(1,5×1,25×0,5) = 15.000:0.9375 = 16.000
24) 4×4×10 = 400 cm²
JAWABAN :
20. C. V = p × l × t
= 5 × 4 × 3 = 60 cm³
21. A. V = p × l × t
0,25 = p × 2,5 × 0,025
0,25 = p × 0,0625
p = 0,25 : 0,0625 = 4 m
24. A. V = sisi × sisi × tinggi
= 4 × 4 × 10 = 160 cm³
27. A. 3 : 1
29. A. V = 1/3 × La × tinggi
= 1/3 × 3² × 9
= 27 cm³
MAAF KALO SALAH
SEMOGA MEMBANTU :)
