tolong dong jawab soal dwirivel lagi mtk liat ya
= ( 5 x 5 ) x 6
= 25 x 6
= 150cm²
30. 2 ( p x l ) + ( l x t ) + ( p x t )
= 2 ( 10 x 8 ) + ( 8 x 5 ) + ( 10 x 5 )
= 2 ( 80 ) + ( 40 ) + (50)
= 160 + 80 + 100
= 340 cm²
L permukaan kubus =6×5^2=6×25=150 cm^2
jawabanya C.
30.L permukaan balok=2((p×l)+(p×t)+(l×t))
L permukaan balok=2((10×8)+(10×5)+(8×5))
L permukaan balok=2(80+50+40)= 340 cm^2
jawabanya C.
