Answer: The second option.

Step-by-step explanation:

1. Calculate the first volume assuming that the figure is completed (with no missing part). Therefore, you must apply the formula for calculate the volume of a square prism:

V_A=s^{2}*h

Where s is the side of the base and h is the height.

2. Then:

V_A=(40cm)^{2}*50cm=80,000cm^{3}

4. The volume of the missing part is calculated with the formula of a rectangular prism:

 V_B=l*w*h

Where l is the lenght, w is the width and h is the height. Then:

V_B=(40cm)(40cm-35cm)(50cm-25cm)=5,000cm^{3}

5. Therefore, you must subtract both volumes to obtained the volume of the figure:

V_f=80,000cm^{3}-5,000cm^{3}=75,000cm^{3}

Is the circle inside the hexagon or hexagon inside the circle?
nexus9112 [7]

It could be either, we need more info. How big are each? If it doesn't say, then it's a trick question. Throw Schrodinger's cat at it or something.
