a rectangular prism has a length of 7 cm, a width of 4 cm, and a height of 2 1/2 cm.

the prism is filled with cubes that have edge lengths of 1/2 cm.

how many cubes are needed to fill the rectangular prism?

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
