Answer:
The total volume of the stairwell is 45 ft³
Step-by-step explanation:
The short stairwell is made of solid concrete.
The height and width of each step is 3 ft and the length is 5 feet.
As we know the shape of stairwell is like a cuboid.
whose,
Length = 5 ft
Height = 3 ft
Width = 3 ft
Volume of cuboid = l x b x h
Volume of stairwell = 5 x 3 x 3
= 45 ft³
Hence, The total volume of the stairwell is 45 ft³
