volume of square middle = 12 x 12 x 7 = 1008

 if you put the 2 ends together it would be a cylinder so volume for that is:

3.14 x 6^2 x 7 = 791.28

1008 + 791.28 = 1799.28  round it off to 1800 mm^3


So D is the correct answer

Answer:

4th option is correct.

Step-by-step explanation:

Here in the given image, we can see that there can be 2 figures if separated. A cuboid with dimensions 12*12*7 and a cylinder with radius as 6 mm and height as 7 mm.

We will first find the volume of cuboid.

V = [tex]12\times12\times7[/tex] = 1008 cubic mm

Now, volume of cylinder is given as : [tex]\pi r^{2} h[/tex]

[tex]3.14\times6^{2}\times7[/tex] = 791.28 cubic mm

Now adding both the volumes to get the volume of complete figure:

V = [tex]1008+791.28=1799.28[/tex] cubic mm

Now this value is closest to option 4th : 1800 cubic mm.

Therefore, last option is true.
