jawab ya pake cara!

43)Volume=Luas alas×tinggi
=1/2×15×15×30
=3375 cm3(B)

44)1-3/4
=4/4-3/4
=1/4

Volume=1/4×p×l×t
=1/4×120×80×65
=1/4×624.000
=156.000 cm3(D)

V = La × t
V = 1/2 × a × t . t
V = 1/2 × 15 × 15 . 30
V = 3.375 cm3

V = p × L × t
V = 120 × 80 × 65
V = 624.000 cm3

terisi 3/4 × 624.000 = 468.000
di isi lagi

624.000 - 468.000
= 156.000 cm3
