Francis filled these prism-shaped containers completely with water. What is the total volume of the water in both containers combined? a
560 m3
b
2,170 m3
c
1,610 m3
d
1,050 m3

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.

there are no multiple choices
