<h3>How to find the volume of a rectangular prism?</h3>The volume of rectangular prism = lwh
where
- l =length
- h = height
- w = weight
Therefore,
height of fluffy cage can be calculate as follows:
4340 = 20 × 14 × h
4340 = 280h
h = 4340 / 280
h = 15.5 inches
height of Kenneth cage can be calculate as follows:
5250 = 20 × 15 × h
5250 = 300h
h = 5250 / 300
h = 17.5 inches
height difference = 17.5 - 15.5 = 2.0 inches
Hence, speedy cage is 2 inches taller than fluffy cage.
