Question

WILL GIVE BRAINLIST PLZZZ HELPPP

Answer 1

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.
