Question

Tolong jawab yah no. 4-8 secepatnya

Answer 1

No1.A.bangun 1 = V = P×L×T
= 14×4×4=224 cm kubik
bangun 2= V = P×L×T
= 20×4×7=560 cm kubik
V Bangunan = 224+560=784 cm kubik

B.bangun 1 = V = P×L×T
=7×12×9,5=798 cm kubik
bangun 2 = V = 12×12×9,5=1368cm kubik

V Bangunan = 1368+798 = 2166 cm kubik

no5.diketahui = P=3m,L= 20cm,T= 12dm
semua diubah menjadi cm,jadi
P= 300cm,L= 20cm,T= 120cm
V=P×L×T=300×20×120=720.000 cm kubik

no6.diketahuiP=25cm,L= 4cm
jadi V= P×L×T
200cm = 25×4×T
200cm = 100 T
T = 200 : 100
= 2 cm

no7.V= P×L×T
576 = 8×L×8
576 = 64 L
L= 576 : 64= 9 dm

no8.diketahuiP=11cm,T=6cm
jadi = 594 : P×T
= 594 : 66
= 9dm
