The floor of Catelyn's bedroom has an area of 123 1/2 square feet. The walls are 9 1/2 feet tall. What is the volume of Catelyn'
saul85 [17]

Answer:

Volume of the Catelyn's bedroom =  1173\frac{1}{4} cubic feet

Step-by-step explanation:

Floor of Catelyn's bedroom has area = 123\frac{1}{2} square feet

                                                              = 123.5 square feet

Height of the walls = 9\frac{1}{2} feet

                               = 9.5 feet

Shape of the room is like a rectangular prism.

Therefore, volume of the bedroom = Area of the rectangular base × Height

                                                           = 123.5 × 9.5

                                                          = 1173.25

                                                          = 1173\frac{1}{4} cubic feet
