Final answer:
The correct answer is option a, which is 1188 ft³. The volume is calculated by multiplying length (11 ft) by width (12 ft) and height (9 ft) of the room.
Step-by-step explanation:
The correct answer is option a. To find the volume of a room, you multiply its length by its width and by its height. In this case, the room has a length of 11 feet, a width of 12 feet, and a height of 9 feet. The calculation for the volume would be:
11 ft × 12 ft × 9 ft = 1188 ft³
Therefore, the volume of the room is 1188 cubic feet, which corresponds to option a.
To find the volume of the room, we need to multiply the length, width, and height of the room together. The dimensions of the room are:
Length: 11 ft
Width: 12 ft
Height: 9 ft
To find the volume, we multiply these dimensions together:
Volume = Length x Width x Height
Volume = 11 ft x 12 ft x 9 ft
Volume = 1188 ft³
Therefore, the volume of the room is 1188 ft³, which corresponds to option a) in the given choices.
