To find the volume of a cube, you can use the formula:
\[ \text{Volume} = s^3 \]
where \( s \) is the side length of the cube.
For this block, the side length is \( 2 \) inches. Plugging in the value:
\[ \text{Volume} = 2^3 = 2 \times 2 \times 2 = 8 , \text{in.}^3 \]
So, the volume of the alphabet block is \( 8 , \text{in.}^3 \).
The correct response is 8 in.³.
