It takes Faucet Z 45 minutes to fill a container measuring 19 cm by 11 cm by 12 cm completely while it takes Faucet C only 30 minutes. How long will it take to completely fill the container with water if both faucets are turned on at the same time and 3 cubic cubes of edges 2 cm, filled with water, are poured into the container? Leave the answer in minutes and round off to 2 decimal places.
Time taken by Faucet Z to fill the container:

45 min → 1 tank
1 min → ¹₄₅ tank

Time taken by Faucet C to fill the container:
30 min → 1 tank
1 min → ¹₃₀ tank

Volume of the container
= 19 x 11 x 12
= 2508 cm³

Volume of 3 cubic cubes
= 3 x (2 x 2 x 2)
= 24 cm³

Time taken by Faucet Z and Faucet C to fill a container:
1 min → ¹₄₅ + ¹₃₀ =⁵₉₀ = ¹₁₈ container

¹₁₈ container → 1 min
1 container → 1 ÷ ¹₁₈ = 1 x ¹⁸₁ = 18 min

Remaining volume of the container to be filled by both faucets 
= 2508 - 24
= 2484 cm³

Time taken to fill the container
= ²⁴⁸⁴₂₅₀₈ x 18
= 17.827751196172
≈ 17.83 min

Answer(s): 17.83 min
