Container F and G are identical containers with the same base area and height. Container F is filled to the brim with water while Container G is empty. After 243 cm³ of water from Container F is poured into Container G, the depth of water in Container G is ¹₉ the depth of water in Container F. If the height of Container G is 27 cm, what is the base area of Container G?
The depth of water is proportional to the volume of water.

After water from Container F is poured into Container G:

Volume of water in Container F : Volume of water in Container G
 9 : 1

1 u = 243

Total volume of Container G
= 9 u + 1 u
= 10 u
= 10 x 243
= 2430 cm³

Base area of Container G
= 2430 ÷ 27
= 90 cm²

Answer(s): 90 cm²
