The aquarium must be filled with water. How many buckets of water are required if the bucket contains 10 liters of water, and the size of the aquarium is 1m length, 0.5m width, and the water level in it should be 70 cm?

The aquarium must be filled with water. Since the water in the aquarium has the shape of a rectangular parallelepiped, we will find its volume by the formula:

V = a ∙ b ∙ c, where length a = 1 m, width b = 0.5 m – the size of the aquarium and the water level in the aquarium should be c = 70 cm = 0.7 m.

To determine how many buckets of water N will be required to fill the aquarium to the required volume, if the bucket contains V₀ = 10 l = 0.01 m ^ 3 of water, we find the ratio:

N = V / V₀ or N = a ∙ b ∙ c / V₀.

Substitute the values of the quantities into the calculation formula:

N = (1 m ∙ 0.5 m ∙ 0.7 m) / 0.01 m ^ 3; N = 35.

Answer: You need 35 buckets of water.
