Question 909340
Uniform Rates rule, R*V=A  usage rate, volume of paint, area of surface covered.
The units for V are gallons (volume) and units for A are square feet (area).


Question is to find v in {{{rv=a}}}.  Variable meanings similar to the basic rule.
The room has six sides to account for area.
a=floor, cieling, two sides, other two sides.
Eight foot cieling part confusing, but seems to mean cieling is 8 feet above the floor.
{{{a=16.5*14+16.5*14+2*16.5*8+2*14*8}}}
{{{a=2*16.5*14+2*16.5*8+2*14*8}}}
{{{a=2(16.5*14+16.5*8+14*8)}}}
{{{highlight_green(a=950)}}}


r = 275 square feet per gallon, given.


{{{rv=a}}}
{{{v=a/r}}}
{{{v=950/275}}}
{{{v=38/11}}}
{{{highlight(v=3&5/11)}}} gallons, or up to but not more than {{{3&1/2}}} gallons approximately
