The water will rise to 8 cm (B)
An aquarium is a space object that is almost the same as a space beam object, where one of the upper sides is uncovered
The beam itself is a 3-dimensional shape formed by three square and rectangular pairs which have 6 sides, 12 edges, and 8 vertices
Volume is a derivative quantity derived from the length of the principal
The unit of volume can be expressed in liters or milliliters or cubic meters
The volume of the aquarium is almost the same as the beam namely:
[tex]\large{\boxed{\bold{V=length\times\:width\times\:height}}}[/tex]
12 liters of water is poured into an aquarium of dimensions 50cm length, 30cm breadth, and 40cm height.
So from here, it can be seen the volume of the aquarium is:
V = 50 x 30 x 40 = 60,000 cm³ = 60 liters
Because there are 12 liters of water being poured, there is as much space as:
60 liters - 12 liters = 48 liters = 48000 cm³
The height of this space is:
[tex]\frac{4800}{50\times30}[/tex]
= 32
Because the height of the aquarium is 40 cm, the height of the water that has been poured is
40 cm - 32 cm = 8 cm
