Tolong dong suhu brainly

Tolong dong suhu brainly

Penjelasan dengan langkah-langkah:

vol = p×l×t

p = vol : (l×t)

l = vol : (p×t)

t = vol : (p×l)

Bagian a

$begin{aligned} sf Volume &= sf 420 : cm^{3} \ sf panjang times lebar times tinggi &= sf 420 : cm^{3} \ sf panjang times 5 : cm times 12 : cm &= sf 420 : cm^{3} \ sf panjang times 60 : cm^{2} &= sf 420 : cm^{3} \ sf panjang &= sf frac{420 : cm^{3}}{60 : cm^{2}} \ sf panjang &= pink{boxed{sf 7 : cm}} end{aligned}$

Bagian b

$begin{aligned} sf Volume &= sf 720 : cm^{3} \ sf panjang times lebar times tinggi &= sf 720 : cm^{3} \ sf 20 : cm times 6 : cm times tinggi &= sf 720 : cm^{3} \ sf 120 : cm^{2} times tinggi &= sf 720 : cm^{3} \ sf tinggi &= sf frac{720 : cm^{3}}{120 : cm^{2}} \ sf tinggi &= pink{boxed{sf 6 : cm}} end{aligned}$

Bagian c

$begin{aligned} sf Volume &= sf 1.200 : cm^{3} \ sf panjang times lebar times tinggi &= sf 1.200 : cm^{3} \ sf 30 : cm times lebar times 5 : cm &= sf 1.200 : cm^{3} \ sf 150 : cm^{2} times lebar &= sf 1.200 : cm^{3} \ sf lebar &= sf frac{1.200 : cm^{3}}{150 : cm^{2}} \ sf lebar &= pink{boxed{sf 8 : cm}} end{aligned}$

Bagian d

$begin{aligned} sf Volume &= sf 1 : liter \ sf panjang times lebar times tinggi &= sf 1.000 : cm^{3} \ sf 25 : cm times 8 : cm times tinggi &= sf 1.000 : cm^{3} \ sf 200 : cm^{2} times tinggi &= sf 1.000 : cm^{3} \ sf tinggi &= sf frac{1.000 : cm^{3}}{200 : cm^{2}} \ sf tinggi &= pink{boxed{sf 5 : cm}} end{aligned}$

Bagian e

$begin{aligned} sf Volume &= sf 1,6 : dm^{3} \ sf panjang times lebar times tinggi &= sf 1.600 : cm^{3} \ sf panjang times 10 : cm times 10 : cm &= sf 1.600 : cm^{3} \ sf panjang times 100 : cm^{2} &= sf 1.600 : cm^{3} \ sf panjang &= sf frac{1.600 : cm^{3}}{100 : cm^{2}} \ sf panjang &= pink{boxed{sf 16 : cm}} end{aligned}$
