Question

Martens got a small aquarium forgot her birthday. The aquarium is a right rectangular prism 18.5cm long by 15cm wide. Martens put 3885cm cubes of water in the aquarium. How deep is the water?

Answer 1

Depth of Martens aquarium water = 14 cm.

Explanation:

Given:

An aquarium,which is a right rectangular prism.

Length of the aquarium,
`l` = 18.5 cm

Width of the aquarium,
`b` = 15 cm

Volume of the aquarium,
`V` = 3885 cm cubes

We have to find the depth of the aquarium.

Let the depth be
`h` cm.

Note:

Volume of the rectangular prism,V=lbh.

⇒
`V` =
`l* b* h`

⇒
`h=(V)/(l* b)`

⇒ Plugging the values.

⇒
`h=(3885\ cm^3)/(18.5\ cm* 15\ cm)`

⇒
`h=14` cm

So,

The depth of the aquarium water is 14 cm.
