Answer:
13 buckets
Step-by-step explanation:
To find the area of the closet, 7 x 10 x 9 = 630. The amount of square feet in the closet is 630. If one bucket of paint only covers about 100 square feet and he was recommended to do 2 coats, that means he will need to paint 1260 square feet total, including both coats. If one bucket covers 100 square feet, then he will need to buy 13 buckets of paint total.

Step-by-step explanation:
![3x+4=-15](https://tex.z-dn.net/?f=3x%2B4%3D-15)
![3x+4-4=-15-4](https://tex.z-dn.net/?f=3x%2B4-4%3D-15-4)
![3x=-19](https://tex.z-dn.net/?f=3x%3D-19)
![\frac{3x}{3}=\frac{-19}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B3x%7D%7B3%7D%3D%5Cfrac%7B-19%7D%7B3%7D)

Answer:
256 ft²
Step-by-step explanation:
4 lateral faces + 2 bases
The total area
![=2 \times (12 \times 4) + 2 \times (12 \times 5) + 2 \times (5 \times 4)](https://tex.z-dn.net/?f=%20%3D2%20%5Ctimes%20%2812%20%5Ctimes%204%29%20%2B%202%20%5Ctimes%20%2812%20%5Ctimes%205%29%20%2B%202%20%5Ctimes%20%285%20%5Ctimes%204%29)
![= 96 + 120 + 40](https://tex.z-dn.net/?f=%20%3D%2096%20%2B%20120%20%2B%2040)
![= 256](https://tex.z-dn.net/?f=%20%3D%20256)
The dividend is 492.
Hope this helps. ;)
