Answer:
B. 81 cubic inches
Step-by-step explanation:
Since this is an irregular 3 dimensional object, I will cut it into a 3 by 3 by 3 cube and a 6 by 3 by 3 rectangular prism.
Solving for the cube:
3*3*3=
9*3=
27 units or in this case inches³
Solving for the rectangular prism:
6*3*3=
18*3=
54 units or in this case inches³
To get the total volume, we need to add the cube and rectangular prism's volume together:
54+27=81 inches³
Our answer is B. 81 cubic inches.
