Question

A fish tank is filled with water.The tank holds 150 gallons.Each cubic foot of water contains about 7.5 gallons.The rank is 5 feet long and 3 feet high.what is the width of the tank

Answer 1

Width =
`1(1)/(3)` ft

Explanation:

The tank holds 150 gallons of water.

7.5 gallons holds 1 ft³ of water.

So 150 gallons will hold;

`(150)/(7.5)` × 1 ft³ = 20 ft³

The volume of the tank = Length(l) × Width(w) × Height(h) = 20 ft³

i.e 5 ft × w × 3 ft = 20 ft³

15w ft² = 20 ft³

w =
`(20 ft^3)/(15 ft^2)` =
`1(1)/(3)` ft
