To find the volume of a rectangular prism, you can use the formula:
\[ \text{Volume} = \text{Length} \times \text{Width} \times \text{Height} \]
Given the dimensions of the prism are 8 inches, 12 inches, and 7 inches, we can calculate the volume as follows:
\[ \text{Volume} = 8 , \text{inches} \times 12 , \text{inches} \times 7 , \text{inches} \]
Now, let's do the multiplication step-by-step:
-
Multiply the first two dimensions: \[ 8 \times 12 = 96 , \text{square inches} \]
-
Now, multiply that result by the third dimension: \[ 96 \times 7 = 672 , \text{cubic inches} \]
Therefore, the volume of the prism is 672 cubic inches.
