moho di jawab pake peroses kakak
Jawaban:
7. V = 1/3 x luas alas x tinggi
V = 1/3 x (s x s ) x t
V = 1/3 x (4 x 4) x 12
V = 1/3 x 16 x 12
V = 1/3 x 192
V = 64 cm³
8. Lp = luas alas + jmlh luas sisi tegak
Lp = (s x s) + 4 (1/2 x s x sisi tegak)
Lp = (4 x 4) + 4 (1/2 x 4 x 14)
Lp = 16 + 4 (28)
Lp = 16 + 112
Lp = 128 cm²
