wat yo mean by don't solve the bottom
oh well

so we need surface area

we need top rectangle, 2 side triangles, back rectangle and bottom rectangle

top is 5 by 25 and 1/5, the raea is 25 and 1/5 times 5=126 square feet
triangles are the same
but which one is the height?
hmm
I'm going to assume the 25ft is height
so base is 25/12 ft
2 triangles so
2 times 1/2 times 25 times 25/12=625/12 square feet
back
25/12 feet by 5ft or 125/12 ft²

bottom is 25 by 5ft or 125 sqaurefeet


total

126+625/12+125/12+125=627/2 squaer feet or 313.5 sqquare feet
so every hundred needs 1 quart

313.5/100=3.135
round up becase you can't buy 0.135 quart (or can you?)
4 quarts
