一舊1萬公斤既石頭有幾大？

1萬公斤 = 10,000kg
10,000kg = 10,000,000g

佢既體積:
=10,000,000g / 3g
=3,333,333 cm^3 , corr. to the nearest integer

因為係立方體...所以佢既底, 高, 闊都一樣
當佢既高係x cm
x^3 = 3,333,333
x = 149.38 ,corr. to 2 d.p.

所以佢既高度係 149.4cm 咁高到

請勿抄襲!!

3 g/cm^3=0.003 kg/cm^3
0.003 kg/1 cm^3=10000 kg/y
y=3333333.33 cm^3

有幾大,n禁大
