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