Question

Mario's father is building a skateboard ramp in the shape of a triangular prism. Mario has agreed to paint the ramp once its finished if a quart of paint covers 85 ft how many quarts of paint will mario need to buy

Answer 1

Answer:

6

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  

Please have a look at the attached photo.

My answer:

We need to find the total surface area of the building a skateboard ramp  without its bottom.

• The Area of the slope: 10.5*25 = 262.5 $ft^{2}$
• The Area of the two triangles: 2 ($\frac{1}{2} 7*24$) = 168 $ft^{2}$
• The Area of the back: 10.5*7 = 73.5 $ft^{2}$

So the total surface area is: 262.5 + 168 +73.5 = 504 $ft^{2}$

Hence, the number quarts of paint will mario needs to buy is:

504/85 ≈ 6

Hope it will find you well
