a.
175.1 cm^3
b.
191.1 cm^3
c.
255.1 cm^3
d.
355.1 cm^3

select the best answer from the choices provided

B.) 191.1 cubic cm.

Step-by-step explanation:

First find the area of the rectangular prism. Because the formula is l * w * h, this becomes = 149.1.

For the volume of a pyramid, the equation is . We already know the height, and because it's sitting on top of the rectangular prism, the base should have the same area. In other words, if the prism has a base of 7*6, then the pyramid can be found through . 7 Multiplied by 6 is 42, and since it's multiplied but also divided by 3, they cancel out, leaving only 42.

The sum of both of these shapes is 191.1 cm³.

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
