Luas alas = s x s = 10 x 10 = 100cm² Volume = 1/3 x L.a x t 400 = 1/3 x 100 x t 100 x t = 400 x 3 100t = 1200 t = 12cm Tinggi Δ = √ 12² + 5² = √ 144 + 25 = √ 169 = 13cm
= 10 x 10
= 100cm²
Volume = 1/3 x L.a x t
400 = 1/3 x 100 x t
100 x t = 400 x 3
100t = 1200
t = 12cm
Tinggi Δ = √ 12² + 5²
= √ 144 + 25
= √ 169
= 13cm
