Question

Angelfish need at least 7

gallons of water to live.
Four friends have four
different sized fish tanks
(rectangular prisms). If
each tank has the
following dimensions,
which children have a
tank big enough for an
angelfish?
Hint: 1 gallon = 231 cubic inches
Children
Caroline
Thomas
Henry
Kym
Tank dimensions (inches)
16 x 14 x 9
15 x 7 x 9.5
14 x 12 x 9.5
14 x 11 x 10.5

Answer 1

Answer: Caroline and Kym

Explanation:

To determine which children have a tank big enough for an angelfish, we need to calculate the volume of each tank in cubic inches and convert it to gallons.

Caroline's tank: Volume = length x width x height = 16 x 14 x 9 = 2,016 cubic inches. Converting to gallons: 2,016 / 231 = 8.72 gallons. Caroline's tank is big enough for an angelfish.

Thomas's tank: Volume = length x width x height = 15 x 7 x 9.5 = 999.75 cubic inches. Converting to gallons: 999.75 / 231 = 4.32 gallons. Thomas's tank is not big enough for an angelfish.

Henry's tank: Volume = length x width x height = 14 x 12 x 9.5 = 1,596 cubic inches. Converting to gallons: 1,596 / 231 = 6.90 gallons. Henry's tank is not big enough for an angelfish.

Kym's tank: Volume = length x width x height = 14 x 11 x 10.5 = 1,683 cubic inches. Converting to gallons: 1,683 / 231 = 7.28 gallons. Kym's tank is big enough for an angelfish.

Therefore, Caroline and Kym have tanks that are big enough for an angelfish. Thomas and Henry do not.
