Answer:
$16
Step-by-step explanation:
To find the cost per square foot we have to solve the given equation for x:
6.4x - 3.7x = 43.2
2.7x = 43.2
Divide both sides of the equation by 2.7 to isolate the x:
2.7x/2.7 = 43.2/2.7
x = 16
The sheet metal costs $16 per square foot.

Triangle area = 6 * 8 / 2 = 24 square inches
Prism Surface Area = 2 * triangle area + height * (side a + side b + side c)
228 = 2 * 24 + height * (6 + 8 + 10)
228 -48 = height * 24
height = 180 / 24
height = 7.5
