If a gas can has dimensions of 10 inches long, 8 inches wide, and 12 inches high, what is its volume in cubic inches?

To find the volume of a rectangular prism, such as a gas can, the formula to use is length multiplied by width multiplied by height.

In this case, the given dimensions are 10 inches for length, 8 inches for width, and 12 inches for height. Performing the calculation:

[ Volume = Length \times Width \times Height ]

Substituting in the values:

[ Volume = 10 , \text{inches} \times 8 , \text{inches} \times 12 , \text{inches} ]

First, multiply the length (10 inches) by the width (8 inches):

[ 10 \times 8 = 80 , \text{square inches} ]

Next, take this result and multiply it by the height (12 inches):

[ 80 \times 12 = 960 , \text{cubic inches} ]

Thus, the volume of the gas can is correctly calculated to be 960 cubic inches. This confirms that the correct answer is indeed 960. Understanding this procedure is essential in solving volume problems related to three-dimensional objects, particularly in scenarios where accurate volume measurements are crucial.
