To find the volume of the first-aid kit, you can use the formula for the volume of a rectangular prism:
\[ \text{Volume} = \text{length} \times \text{width} \times \text{height} \]
In this case, the dimensions of the first-aid kit are:
- Length = 7 inches
- Width = 10 inches
- Height (Depth) = 3 inches
Now, plug in the values:
\[ \text{Volume} = 7 , \text{in} \times 10 , \text{in} \times 3 , \text{in} \] \[ \text{Volume} = 210 , \text{in}^3 \]
So, the volume of the first-aid kit is 210 in.³.
The correct response is 210 in. cubed.
