sp2606 [1]

Answer:

Depth of Martens aquarium water = 14 cm.

Step-by-step 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\times b\times h

⇒ h=\frac{V}{l\times b}

⇒ Plugging the values.

⇒ h=\frac{3885\ cm^3}{18.5\ cm\times 15\ cm}

⇒ h=14 cm

So,

The depth of the aquarium water is 14 cm.
