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.
To know the amount of eights you want to get something that looks like ?/8. Basically, the bottom number needs multiplying by 2 (8 divided by 4 is 2). To keep the fraction accurate you multiply by 2 the top and bottom number so you get:
<span>3/4=(3x2)/(4x2)=6/8</span>
<span>divide 65.56/22= 2.98 per gallon. </span>
