= 22/7 x 60 cm x 60 cm x 140 cm
= 1584000 cm³
Q = 250 cm³/detik
t = V/Q
= 1584000 cm³ / 250 cm³/detik
= 6336 detik
3) a) Luas daratan = 1/4 x 1/2 x 4 x 22/7 x 6380 km
= 10025,71 km
b) V bumi = 4/3 x 22/7 x 6380 x 6380 x 6380
v=πr²xt=3,14x60cm²x140cm
v=1582560cm³⇒liter=dm³⇒1582560÷1000=1582,56l
b.waktu untuk mengisi full=?
debit=volum/waktu⇒250cm³/s=1582560cm³/waktu
waktu=6330,2 s=1 jam 45 menit 12 detik
3.luas daratan=1/3xluas bola/bumi
=1/3x(4πr²)=1/3x(801328x638)=4(42603726)
volume bumi=4/3πr³=(maaf kurang tau)
