My intention was to start a debate as to why any country should accept the US dollar as the world reserve currency particulalry as to why any country should entrust the health of its economy to a secretive private banking cartel based in the US outside the control of the US Government.
if a gallon of paint covers 400 sq ft, how many gallons will you need to paint a 10'x12' room including the ceiling with 4 walls and an 8' ceiling with one coat of paint?
Report Abuse. Depends on how much wall space you have to cover. A gallon of paint covers about 400 sq. ft. and costs about $25. a gallon. So you need to start measuring, take your measurements for each room and the paint personnel will help you figure out how much paint you need per room.ou can figure $1.00 per sq. ft. which includes materials (average quality paint $23 per gallon) this however, this price does not typically include ceilings or doors and baseboards. This is assuming you are asking how much for someone else to do it.
