+136 I have to paint one side of a wall. The wall is $15$ meters tall and $60$ meters long. Each gallon of paint covers $400$ square feet. If a foot is approximately $0.3048$ meters, then what is the smallest whole number of gallons I can buy and have enough paint to cover the whole wall?
+943 We can use simple conversions and calculations to solve this problem.
We first find the total area needed, then divide it by 400, before doing conversions.
Thus, we have
\( [ 15 * 60 *1 / 400] = 9/4\)
Converting to meters, we have
\(\frac{9/4}{(0.3048^2)} \approx 25\)
so our answer is just 25.
Thanks! :)
