The volume of concrete the worker needs in cubic yards is 5 cubic yards of concrete
Calculating volume
From the question, we are to determine the volume of concrete the worker needs in cubic yards
From the given information,
Length = 28 ft = 28/3 yards
Width = 12 ft = 4 yards
Height = 4 in = 1/9 yard
Thus, the volume of concrete needed
V = 28/3 × 4 × 1/9
V = 112/27
V = 4.148 cubic yards
Since the construction worker cannot buy a fraction of a cubic yard of concrete,
The volume of concrete the worker needs in cubic yards is
V ≅ 5 cubic yards of concrete
Hence, the volume of concrete the worker needs in cubic yards is 5 cubic yards of concrete
