Answer: 6 yards by 14 yards by 0.5 yardÂ
Step-by-step explanation:
Given that the concrete will fill a space that is a right rectangular prism that is 18 feet wide, 42 feet long
The cubic feet of the space =
242 Ă— 18 Ă— 6/12= 378 cubic ft
Given that 1 foot = 12 inches and 1 yard = 3 feet
6 yards by 14 yards by yard will give
( 6Ă—3 )Ă—(14 Ă— 3)Ă—(0.5Ă—3) = 378 cubic ft
the dimensions of this space must be equal to the concrete dimensions space that is a right rectangular prism
