Volume Limas segitiga = (1/3) x (luas alas segitiga) x t = (1/3) x (0.5 x 10 x 10) x 15 = 150 cm^3. Luas permukaan Limas segitiga = luas alas + luas sisi miring = 10 x 10 + 3 x (10 x 15 / 2) = 100 + 45 = 145 cm^2.
Volume Limas segitiga = (1/3) x (luas alas segitiga) x t = (1/3) x (0.5 x 6 x 9) x 15 = 135 cm^3.
Volume Limas segitiga = (1/3) x (luas alas segitiga) x t = (1/3) x (0.5 x 16 x 16) x 14 = 512 cm^3. Luas permukaan Limas segitiga = luas alas + luas sisi miring = 16 x 16 + 3 x (16 x 8 / 2) = 256 + 96 = 352 cm^2.
Volume Limas segi empat = (lebar x tinggi x sisi) / 3 = (7 x 10 x 9) / 3 = 140 cm^3.
Jadi gini...............
Volume Limas segitiga = (1/3) x (luas alas segitiga) x t = (1/3) x (0.5 x 10 x 10) x 15 = 150 cm^3. Luas permukaan Limas segitiga = luas alas + luas sisi miring = 10 x 10 + 3 x (10 x 15 / 2) = 100 + 45 = 145 cm^2.
Volume Limas segitiga = (1/3) x (luas alas segitiga) x t = (1/3) x (0.5 x 6 x 9) x 15 = 135 cm^3.
Volume Limas segitiga = (1/3) x (luas alas segitiga) x t = (1/3) x (0.5 x 16 x 16) x 14 = 512 cm^3. Luas permukaan Limas segitiga = luas alas + luas sisi miring = 16 x 16 + 3 x (16 x 8 / 2) = 256 + 96 = 352 cm^2.
Volume Limas segi empat = (lebar x tinggi x sisi) / 3 = (7 x 10 x 9) / 3 = 140 cm^3.
