Question

tolonh jawab secepatnya ya,,jngn lupa pakai caranya..​

Answer 1

Penjelasan dengan langkah-langkah:

1).Lp kubus = 6×S²

=6×12×12

=864 cm²

2).Lp balok = 2×{(p×l)+(p×t)+(l+t)}

= 2×{(12×8)+(12×10)+(8×10)}

=2×(96+120+80)

=2×(296)=592 cm²

3).Luas tabung = pi r²t

=22/7×14²×20

=22×2×14×20

=44×14×20

=616×20

=12.320cm³

4).Lp= L alas×(4× L segitiga)

=12×12+(4×12×16/2)

=144+(4×96)

Lp= 144+384=528cm2

5).Lp limas =2×L alas + k alas × t

=2×(6×8/2)+(6+6+6)×12

=2×24+18×12

=48+216 = 264cm²
