I need help please. Will give brainliest

volume of cuboid=l×b×h=8×4×4=128cm³

volume of half cylinder=1/2(π(d/2)²h)=1/2×22/7×8=12.57cm²

volume of figure=128-12.57=115.43cm²

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.

answer is 12345678900987654321234567890987654321
