Answer:

160

Step-by-step explanation:

In this question, we dont know the lenth and the width of the prism, so allow me to assume this two values and the large wooden prism is the rectangular one with the:

  • lenth is 10ft
  • width is 4ft

So the area of it's side is: 10*4 = 40

We have to paint 4 sides, so the are is: 40*4 = 160

A can of spray paint costs $4.00 and will cover 40 square feet, so the number of spraies is: 160/40 = 4

The total cost = 4 *40 = 160 to paint the box
