Question

Totok akan membuat bak mandi berbentuk balok dengan daya tampung 288 liter. jika perbandingan P:L:T=6:3:2 .maka berapa ukuran bak mandi

Answer 1

6x × 3x × 2x = 288 liter
36x³ = 288
x³ = 288÷366
x³ = 8
x=∛8
x = 2

maka ukuran bak mandi :
panjang = 6x= 6×2 =12
lebar = 3x= 3×2 = 6
tinggi = 2x= 2×2 = 4

Answer 2

288 ltr = 288 dm³
p = 6x ,l = 3x ,t = 2t
V = p.l.t
288= 6x.3x.2x
288 = 36x³
288:36 =x³
8 = x³ ,maka 2³ = x³
x = 2 dm
p =6x
= 6.2=12dm=120cm
l = 3x
= 3.2 =6 dm=60cm
t = 2 x
= 2.2 =4 dm=40cm
