Problem: An aquarium can hold 3,744 cubic inches of water. Ben fills the aquarium full of water. Water weighs about 0.036 pounds per cubic inch. Which 10 estimate of the weight of the water in the aquarium is closest to the exact value? 165 pounds​

Solution:

Resolve for x:

`x\text{ = }\frac{3,744inch^3\text{ x 0.036 Lb}}{1\text{ inch}^3}`

That is equivalent to say:

`x\text{ = }\frac{3,744inch^3\text{ x 0.036 Lb}}{1\text{ inch}^3}\text{ = }134.78\text{ = 135 Lb}`
