The short stairwell is made of solid concrete. the height and width of each step is 3 ft and the length is 5 feet. what is the total volume of the stairwell?

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

e) none of the above because the measure of angle cba is 101°
