11) P rusuk setelah diperbesar = Panjang = 20 X 2 = 40 Lebar =18 X 2 = 36 Tinggi =10 X 2 = 20 Volume = 40 X 36 X 20 = 28.800
12) V = p x l x t 385 = 11 x 5 x (3+x) 385 = 55 x (3+x) 385/55 = 3+x 7 = 3+x x = 7-3 =4 t = 3+ 4 = 7 Lp= 2((pxt)+(lxt)+pxl) =2((11x7)+(5x7)+(11x5)) = 2 (77 + 35 + 55) = 2 (167) = 334
Panjang = 20 X 2 = 40
Lebar =18 X 2 = 36
Tinggi =10 X 2 = 20
Volume = 40 X 36 X 20 = 28.800
12) V = p x l x t
385 = 11 x 5 x (3+x)
385 = 55 x (3+x)
385/55 = 3+x
7 = 3+x
x = 7-3 =4
t = 3+ 4 = 7
Lp= 2((pxt)+(lxt)+pxl)
=2((11x7)+(5x7)+(11x5))
= 2 (77 + 35 + 55)
= 2 (167) = 334
