The volume of a rectangular prism can be found by multiplying the three side lengths. A box in the shape of a rectangular prism has dimensions (a-1) cm, (a+1) cm, and (a+ 4) cm. Find the volume of the box.

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte
