A. 3 cubic yards
B. 6 cubic yards
C. 9 cubic yards
D. 12 cubic yards

Answer 1

To pour a basement floor measuring 24'x54' and 4'' thick, you would need 16 cubic yards of concrete.

Step-by-step explanation:

To calculate the amount of concrete needed to pour a basement floor, we first need to calculate the volume of concrete required. The volume can be calculated by multiplying the length, width, and thickness of the floor. In this case, the length is 24 feet, the width is 54 feet, and the thickness is 4 inches, which is equivalent to 1/3 feet. So, the volume of concrete needed is 24 x 54 x (1/3) cubic feet. To convert this volume to cubic yards, we divide by 27, since there are 27 cubic feet in a cubic yard.

Calculating the volume of concrete needed:

1. Volume = Length x Width x Thickness
2. Volume = 24 feet x 54 feet x (1/3) feet
3. Volume = 432 cubic feet

Converting the volume to cubic yards:

1. Cubic Yards = Cubic Feet / 27
2. Cubic Yards = 432 cubic feet / 27
3. Cubic Yards = 16 cubic yards

Therefore, 16 cubic yards of concrete are needed to pour the basement floor.
