Anna's bedroom is in the shape of a right rectangular prism. The floor has an area of 120 square feet. The walls are 8 feet high. What is the volume of Anna's bedroom? Answer options with 4 options A. 15 cubic feet B. 128 cubic feet C. 960 cubic feet D. 7680 cubic feet

C. 960 cubic feet

Step-by-step explanation:

Given;

area of the bedroom floor = area of the base of the right rectangular prism, A = 120 square feet

height of the bedroom wall = height of the right rectangular prism, h = 8 feet

Volume of the bedroom = Volume of the right rectangular prism

Volume of the right rectangular prism = A x h

Volume of the right rectangular prism = 120 ft² x 8 ft

Volume of the right rectangular prism = 960 ft³

Therefore, the correct option is "C. 960 cubic feet"

7/1; 4/2=2;8/1

7 is rational number because 7/1 = 7

8 = 4 x 2 = 4/1 x 2/1 and both rational.
