Answer:
14cm
Step-by-step explanation:
Martelene bought a small aquarium to celebrate her birthday.
The aquarium has a length of 18.5cm, width of 15cm and a volume of 3885 cubic centimeters.
From the question above we are required to calculate the depth of the water in the aquarium
Let A represent the depth of the water in the aquarium
Volume= length×width×height
3885= 18.5 × 15 × A
3885= 277.5A
Divide both sides by the coefficient of A which is 277.5
3885/277.5= 277.5A/277.5
A = 3885/277.5
A= 14cm
Hence the water is 14cm deep into the aquarium.
