Answer:
x=75
Step-by-step explanation:
*The width in your question - I assumed it is refers to the height of the triangle base.
Volume of a triangle prism = base area x height
The base is a triangle:
Volume of a triangle prism = (1/2 x base x height₁) x height₂
Plug in the values and solve for height₂:
50.4 = (1/2 x 9 x 3.5) x height
50.4 = 15.75 x height
height = 50.4 ÷ 15.75
height = 3.2 units
-----------------------------------------
Answer: Height = 3.2 units
-----------------------------------------
.45 * 120 = 54
.072 * 54 = 3.888
54 + 3.888 = 57.888= $57.89
