The volume of rectangular prism is the product of its length, width and height.
So the volume V of prism with length
yards, width 
yards and height of 4 yards will be:
Thus the volume of prism as a mixed number in simplest form will be
cubic yards
So the volume V of prism with length
Thus the volume of prism as a mixed number in simplest form will be
The correct axis of symmetry is x = -1.
Explanation:
Our equation is
.
This is in vertex form, which is
y = a(x-h)² + k, where (h, k) is the vertex.
In our equation, h corresponds with -1 and k corresponds with -3, making the vertex (-1, -3).
The axis of symmetry is the x-coordinate of the vertex; this makes the axis of symmetry for this equation x = -1.
