Answer:im not certain but i think its about 18 galons
Step-by-step explanation: well first the area of the top, each triangle side thing is 112.5 in squared and then multiply by 4 which is 450, so you add it with the area of the rectangles (each side of the botome) and then the final base, so the equation would look like this 450+(30*15)4+(15*15) which is 2475, then divide it by the amount of space each gallon of paint can cover 143 ft squared, which is about 18 (i cant calculate the decimals because each gallon of paint is a gallon, not anything in between) so thats it (sorry for spelling errors)
