Which statement is true when justifying the formula to find the volume of a right rectangular prism?
1. The base of the prism is a square, so the volume formula multiplies twice the length of the base times the height.
.
2. The base of the prism is a rectangle, so the volume formula multiplies the area of the base by the height of the prism.
3. The base of the prism is a rectangle, so the volume formula multiplies twice the area of the base times the height.
4. The base of the prism is a rectangle, so the volume formula multiplies the length of the base times the length of the height.
