The portion of a swimming pool that is below the full water line measures 12 feet by 30 feet by 6 feet deep. What is the volume of water in the swimming pool when it is full, expressed in cubic yards? (1 cu yd =27 cu ft)
a.60 cu yd
b. 72 cu yd
c.74.6 cu yd
d. 80 cu yd
What is 4 * 10 * 2?
Or
What is 12 * 30 * 6 divided by 27?
To find the volume of water in the swimming pool when it is full, we need to calculate the volume of the portion below the full water line and convert it to cubic yards.
The dimensions of the portion below the full water line are given as 12 feet by 30 feet by 6 feet deep. To find the volume, we multiply these dimensions together:
Volume = Length x Width x Depth
= 12 ft x 30 ft x 6 ft
= 2160 cubic feet
Next, we need to convert cubic feet to cubic yards. Since 1 cubic yard is equal to 27 cubic feet, we divide the volume in cubic feet by 27:
Volume in cubic yards = Volume in cubic feet / 27
= 2160 cubic feet / 27
= 80 cubic yards
Therefore, the volume of water in the swimming pool when it is full, expressed in cubic yards, is 80 cubic yards. Therefore, the correct answer is (d) 80 cu yd.
