a. panjang rusuk b.luas permukaan c.volume d. panjang diagonal ruang
Brillianttta. panjang rusuk = 188/12 = 14 cm b. Luas permukaan = 6 x r x r = 6 x 14 x 14 = 6 x 196 = 1176 cm c. V = r x r x r = 14 x 14 x 14 = 2744 cm³ d.panjang diagonasl bidang = r√2 = 14√2 cm
b. Luas permukaan = 6 x r x r = 6 x 14 x 14 = 6 x 196 = 1176 cm
c. V = r x r x r = 14 x 14 x 14 = 2744 cm³
d.panjang diagonasl bidang = r√2 = 14√2 cm
