yg dijawab nomor 27 - 31

27. V = P × L × T

= 1 m × 0,5 m × 0,8 m

= 0,4 m^3

= 0,4 × 1.000

= 400 dm^3 (A)

28. V = La × T

= (A × T ÷ 2) × T

= (20 × 15 ÷ 2) × 30

= (10 × 15) × 30

= 150 × 30

= 4.500 (D)


29. V = Phi × r^2 × T

= 22/7 × 14^2 × 10

= 22/7 × 196 × 10

= 22 × 28 × 10

= 616 × 10

= 6.160 (C)



31. IPA = 20

MTK = 45

45 - 20

25 (A)
