Answer:
B.) 191.10
Step-by-step explanation:
The given figure has two figures.
1. A cuboid with dimensions 7 cm, 6 cm and 3.55 cm.
2. A pyramid with rectangular base and dimensions 7 cm, 6 cm and 3 cm.
Now we will find the volumes of both the figures, and add them up to get the final volume of complete figure.
The volume of cuboid = [tex]length\times base\times height[/tex]
=> [tex]7\times6\times3.55=149.10[/tex]cubic cm.
And volume of rectangular pyramid = [tex]\frac{1}{3} (width\times base\times height)[/tex]
=[tex]\frac{1}{3}(3\times7\times6)[/tex] = 42 cubic cm
So, the total volume of the figure = [tex]149.10+42=191.10[/tex] cubic cm.
Therefore, the answer is option B.
