Answer:
Rocket can hold maximum 4.5 gallons of water.
Step-by-step explanation:
Volume of the rocket = Volume of the cone on the top + Volume of the cylinder at the bottom
Volume of the cone =
Here r = radius of the circular base
h = height of the cone
Volume =
= cubic inch
Volume of the cylinder =
Here r = radius of the base
h = height of the cylinder
Volume =
= 256π cubic inches
Volume of the rocket =
=
= 1038.82 cubic inches
Since 231 cubic inches volume of a rocket can hold water = 1 gallon
Therefore, 1038.82 cubic inches space can hold water
=
= 4.497
≈ 4.5 gallons
Rocket can hold 4.5 gallons of water.
