Measure the length in feet and the width in feet with the tape measure, then measure the depth in feet with a dip stick if your pond is a square or rectangle.
2
Multiply the length by the width by the depth to get the volume in cubic feet. For example, if your pond is 16 feet long, 8 feet wide and 4 feet deep, multiply 16 by 8 by 4 to get 512 cubic feet.
3
Convert cubic feet to gallons by multiplying the cubic feet by 7.48. In this example, multiply 512 cubic feet by 7.48 to get 3,830 gallons of water in a rectangular pond.

W+y=25 and 9.95w+11.5y=276.65
solve for w in equation one:
w+y=25
w=25-y
then substitute w in equation two and solve for y:
9.95w+11.5y=276.65
9.95(25-y)+11.5y=276.65
1.55y+248.75=276.65
1.55y+248.75-248.75=276.65-248.75
1.55y=27.9
1.55y/1.55=27.9/1.55
y=27.9/1.55=18
y=18
then substitute y=18 into the first equation to solve for x:
w+y=25
rewrite as w=25-y y=18
w=25-18
w=7
then are answer is w=7 and y=18
