Jim is filling his rectangular pig trough full of slop. The trough is 3 ft wide, 8 ft long, and has a depth of 4 ft. One of the piglets jumps in the trough and the slop rises 2.8 inches. What is the volume of the trough?

### Related Information

Question:

A
\(96\text{ }ft^3\)

explanation

To compute for the volume of the trough, use the formula:

\(Volume = L \u00D7 W \u00D7 H\)

\(Volume=8ft \times 4ft \times 3ft= 96ft^3\)

The information about 2.8 inches rise in slop is unnecessary because you are asked to find the *volume of the trough*, not that of the slop.

Be careful to be aware of, and discard, any irrelevant information given in test questions.
