Answer:
Volume of one cube shaped block is, 0.125 cubic feet
Step-by-step explanation:
Volume of a cube(V) is given by:
.....[1]
where a is the edge length of the cube.
As per the statement:
Cube-shaped blocks are packed into a cube-shaped storage container. The edge of the storage container is 2 1/2 feet.
⇒
It is also given that:
The edge length of each block is 1/5 the edge length of the storage container
⇒
Substitute this in [1] we have;
Therefore, volume, in cubic feet, of one cube-shaped block is, 0.125
The volume of the cube-shaped block = (0.5)³ = 0.125 ft³.
Volume of Cube = (edge length of cube)³.
We are given that the edge length of the cube-shaped block is 1/5 of the edge length of the storage container, 2 1/2 ft (2.5 ft).
Therefore, the edge length of the cube-shaped block would be:
1/5 × 2.5 = 0.5 ft.
Volume of the cube-shaped block = (0.5)³ = 0.125 ft³.

Answer:
Because whole numbers are greater than 1 and any number greater than 1 multiplied by it self several times result in a greater number, but proper fractions are numbers less than 1, and a number less than 1 multiplied by it self several times result if a smaller number.
Explanation:
Whole numbers areraised to an exponent , means that such number is multiplied by itself (as many times and the exponent is).
Whole numbers are 1, 2, 3, 4, ....
Number 1 is a special case. When 1 is multiplied by it self the result is 1.
When other whole number (2, 3, 4, 5, ...) is multiplied by it self the result is a greater number. For example, 2 × 2 = 4, 3 × 3 = 9, and so on.
On the other hand, proper fractions, which are those whose numerator is less than the denominator, are less than one, and any number less than 1 multiplied by it self results in a smaller number.
For example: 1/2 × 1/2 = 1/4 or 0.5 × 0.5 = 0.25. This is always true for any proper fraction (a number less than 1).
