Question

Vicente has a prism-like water tank whose base area is 1.2 square meters. He bought 6 goldfish at the store, and the store owner told him to make sure their density in the tank isn't more than 4 fish per cubic meter. Vicente needs to figure out how high to fill the water in the tank.
What is the lowest possible height so the fish aren't too crowded?

Answer 1

Answer:

• 1.25 m

Step-by-step explanation:

Given

• Base = 1.2 m²
• Height = h
• Number of fish = 6
• Density = 4 fish/m³

Minimum volume required:

• 6/4 = 1.5 m³

Lowest water height:

• V= bh
• h = V/b
• h = 1.5/1.2 = 1.25 m
