Explain or show how this is true.
Lin and Noah are packing small cubes into a larger cube with an edge length of
Who would need more cubes to fill the
If Lin and Noah each use their small cubes to find the volume of the larger
A nature center has a fish tank in the shape of a rectangular prism.
The tank is 10 feet long,
What is the volume of the tank in cubic feet? Show your reasoning.
If a rectangular prism has edge lengths of 2 units, 3 units, and 5 units, we can think of it as 2 layers of unit cubes, with each layer having
To find the volume of a rectangular prism with fractional edge lengths, we can think of it as being built of cubes that have a unit fraction for their edge length. For instance, if we build a prism that is
The volume of the prism would be
How do we find its volume in cubic inches? We know that each cube with a
The volume of the prism, in cubic inches, can also be found by multiplying the fractional edge lengths in inches:
If a rectangular prism has edge lengths
This means that if we know the volume and two edge lengths, we can divide to find the third edge length.
Suppose the volume of a rectangular prism is
We can find the third edge length by dividing:
