Today in math we studied length, perimeter, area and volume. Our team was team void team. We were measuring an aquarium with no fish in it. Here is our measurements:
Length (long side) 25 ½ cm
Length (short side) cm
Length of the hight ________cm
Perimeter (side + side + side + side) _______cm
Area (side x side) ________cm2 (square centimeters like little squares at the bottom of a tank or checkerboard)
Volume (side x side x height) ________cm3 (cubic centimeters like how many cubes could fit in the tank)
Water amount (gallons, we'll use an online converter to figure out how many gallons equals our cubic centimeters) ______ gal
How much dechlorinator do we need? - if we use ______ for 1 gallon, we need ________ for our tank.

3 x 5 = 15
3 x 10 = 30
3 x 100 = 300
3 x 99 = 297
3 x 9 = 27
