It takes Faucet U 30 minutes to fill a container measuring 14 cm by 11 cm by 12 cm completely while it takes Faucet Y only 15 minutes. How long will it take to completely fill the container with water if both faucets are turned on at the same time and 4 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 U to fill the container:

30 min → 1 tank
1 min → ¹₃₀ tank

Time taken by Faucet Y to fill the container:
15 min → 1 tank
1 min → ¹₁₅ tank

Volume of the container
= 14 x 11 x 12
= 1848 cm³

Volume of 4 cubic cubes
= 4 x (2 x 2 x 2)
= 32 cm³

Time taken by Faucet U and Faucet Y to fill a container:
1 min → ¹₃₀ + ¹₁₅ =³₃₀ = ¹₁₀ container

¹₁₀ container → 1 min
1 container → 1 ÷ ¹₁₀ = 1 x ¹⁰₁ = 10 min

Remaining volume of the container to be filled by both faucets 
= 1848 - 32
= 1816 cm³

Time taken to fill the container
= ¹⁸¹⁶₁₈₄₈ x 10
= 9.8268398268398
≈ 9.83 min

Answer(s): 9.83 min
