343, 7*7*7, 7^3, Pull up your computer's calculator program. Way easier. Its what I did. volume is height times width times length. 7 times 7 times 7.
A gas will expand to fill its container. This gives the gas the shape and volume of its container.
if matter expands to fill the volume of its container its a suspension.
Solids are rigid and incompressible. Liquids have fixed volume but match their container. Gases completely fill their container.
Volume
Well, since a gas spreads to encompass its container, it should have the same volume as its container.
2cm*2cm*2cm
The volume of a container requires three measures: 18 x 30 is not enough.
Its volume would be 343 cubic feet.
7*7*7 = 343 cubic meters
Volume is a 3-dimensional concept and so it is necessary to have measures in three orthogonal directions: for example, length width and height.
Volume = 3*7*2 = 105 cubic cm
They measure different things. A foot is a linear measure, it measures distance or the length of something. A cubic foot (or any cubic measurement) measures the volume or capacity of a container. How much the 'stuff' the container can hold.
All of those choices are fine. They each are measures of liquid volume.
The volume of a 2x2x2 container is 8.
A container holds volume.
Placing a rock in a container does not alter the volume of the container, although it does occupy some of that volume.
