Question

Bantu jawab soal mtk tentang bangun ruang ini yaa kak (: makasih

Answer 1

Verified answer

D = d1 = d2 = 20 cm
rusuk tegak (rt) = 26 cm

t^2 = (rt)^2 - (1/2.d)^2
t^2 = 26^2 - (1/2×20)^2
t^2 = 26^2 - 10^2
t^2 = 676 - 100
t^2 = 576
t = V576
t = 24 cm


V = 1/3 × La × t
V = 1/3 × (1/2 × d^2) × t
V = 1/3 × (1/2 × 20^2) × 24
V = 1/3 × (1/2 × 400) × 24
V = 1/3 × 200 × 24
V = 1600 cm^3

Jadi volume limas itu adalah 1600 cm^3 (D)
