Answer:
height = 21 m
Explanation:
Assuming you mean to find the height of the prism
the volume (V) of a prism is calculated as
V = Ah ( A is the area of base and h the height )
given V = 1,134 and A = 54
substitute these value into the formula for V
1134 = 54h ( divide both sides by 54 )
=
h , that is
21 = h
the height of the prism is 21 m
