Question

THUIZ
Buktikan jika tinggi balok adalah =
(Luas permukaan - (2×luas alas)) ÷ Keliling alas

Atau
[tex]\sf\displaystyle t=\frac{L_p-(2\times L_a)}{K_{alas}}[/tex]

Answer 1

SOAL 1

___________________________________________

T = [Lp - (2 × La)] ÷ Ka

T = {148 - [2 × (5 × 6)]} ÷ [2(5) + 2(6)]

T = {148 - [2 × 30]} ÷ [10 + 12]

T = {148 - 60} ÷ 22

T = 88 ÷ 22

T = 4 cm

Answer 2

Penjelasan dengan langkah-langkah:

t = Lp – 2 × L.a

K.a

t = 2×(p.l + p.t + l.t) – (2 × p.l)

2×(p + l)

t = 2.p.l + 2.p.t + 2l.t – 2.p.l

2×(p + l)

t = 2.p.t + 2l.t

2p + 2l

t = t.(2p+ 2l)

(2p + 2l)

t = t
