Catherine has $54. She plans to spend more than $20 of the money for a painting canvas. The rest will go toward paints. Each tube of paint costs $8.50. Assume that x represents the number of tubes of paint Catherine can buy. The inequality that best represents this scenario is . The number of tubes of paint Catherine can buy is . The inequality that best represents this scenario is = [Drop down box] 8.5x + 20 > 54, 8.5x 20< 54, 54- 8.5x<20, 54-8.5x > 20
The number of tubes of paint Catherine can buy is=?? [drop down] at least 5, more than 4, less than 4, more than 5

 54x^2+360x+600

Explanation:

One square face has an area of

(length)*(width) = (3x+10)(3x+10) = 9x^2+30x+30x+100 = 9x^2+60x+100

after using the FOIL rule

Multiply that by 6 to get the total area of all 6 faces

6*(9x^2+60x+100) = 54x^2+360x+600

The surface area units are in square feet.
