A rectangular prism that has a width of 3 1/2 inches, a length of 6 1/2 inches, and a height of 2 1/4 inches. The prism is being filed with small cubes with side lengths of the 1/4 in. Use this information to answer the questions below. What is the width of the prism in terms of cubes?

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
