Box volume can be computed by getting the base area
multiplied by the total height.
in formula for volume we have,
V = Base Area x H. Given the Volume of 144 cu in and H = 4.5
in. we can solve for Base Area (BA)
Volume (144 cu in) = BA x Height (4.5 in)
BA = 144 cu in/4.5 in
Base Area = 32 square inches
Answer:
in 2018 it will be 8.09 million
272 fluid ounces of lake water
First calculate the hourly rate, which is the difference of cleaning 2 and 1 rooms:
175-125=50
then calculate the initial value by subtracting the hourly rate from the "1 room" cost:
125-50=75
The initial cost might be something like driving to the place (which is only necessary once), while the rate covers work time or cleaning utensils used.
