Answer:
B) $1,554
Step-by-step explanation:
To calculate the cost of painting the outside walls of the rectangular prism metal building, we need to find the total surface area of the walls and then multiply it by the cost of paint per square foot.
The formula for the surface area of the four walls of a rectangular prism is:
[tex]A=2h(l+w)[/tex]
The dimensions of the building are:
Now, substitute these values into the formula:
[tex]A=2\cdot 14(100+50)\\\\A=2\cdot 14(150)\\\\A=2\cdot 2100\\\\A=4200\; \sf ft^2[/tex]
So, the total surface area of the four walls is 4200 square feet.
Multiply this by the cost of the paint per square foot:
[tex]\textsf{Cost to paint}=4200 \cdot \$0.37\\\\\textsf{Cost to paint}=\$1554[/tex]
Therefore, it would cost $1,554 to paint the outside walls of the building.
