Answer:
So we need about 2 gallons
Step-by-step explanation:
The lateral surface area is found by
LSA = Perimeter * height
= 2*(l+w) * h
The length is 12 the width is 15 and the height is 9
= 2(12+15) * 9
= 2* (27) * 9
= 486 ft^2
If each gallon covers 250 ft^2
Take 486/250
1.944 gallons of paint are needed.
We need to buy the paint in gallons
So we need about 2 gallons
