Answer: 512 in.³
Step-by-step explanation: To find the volume of a cube, first start with writing down the formula for the volume of a cube which is as followed.
Volume = Length × Width × Height
In this problem, our prism is a cube. Since the length, width, and height of a cube are all equal, we can find the volume of a cube by simply multiply side times side times side or s³.
Volume = Length x Width x Height
Volume = (8) (8) (8)
Volume = 512 in³.
Therefore, the volume of the cube is 512 in.³.
