dari 37 sampe 40 pake cara y gan!

37. luas balok
L= 2(p.l +p.t + l.t)
= 2(10x6 + 10x5 + 6x5)
= 2( 60+50+30)
= 2 x 140
= 280 cm²
38. 1 rim = 500 lembar
58 rim= 58 x 500
= 29.000
29000 : 580 = 50 lembar
39. jumlah nilai = 150 +110+115+210+90+120+185
=980
jumlah data = 7
nilai rata rata = 980 : 7
=140 telur per hari
40. .....?
