Answer:
13.63 cubic yards
Step-by-step explanation:
we are asked to find the volume of the slab in cubic yards, hence we have to be sure that all the lengths are expressed in yards first. We use the following conversions:
1 ft = 1/3 yard
1 in = 1/36 yard
Length = 23 ft = 23 x (1/3) = 23/3 yards
Width = 24 ft = 24 x (1/3) = 8 yards
thickness = 8 in = 8 x (1/36) = 8/36 = 2/9 yards
hence volume = Length x Width x Thickness
= (23/3) x 8 x (2/9)
= 13.63 cubic yards
