Calculate the volume of the composite solid. a.) 175.1 b.) 191.1 c.) 255.1 d.) 355.1

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 =

=> cubic cm.

And volume of rectangular pyramid =

= = 42 cubic cm

So, the total volume of the figure = cubic cm.

Therefore, the answer is option B.
