A cube with a volume of 64 cubic meters is scaled by a factor of 5. What is the volume of the modified cube in cubic meters? (Note: do not include the units in your answer.)



Answer :

To find the volume of the modified cube after it has been scaled by a factor of 5, follow these steps:

1. Determine the original volume of the cube:
The original volume is given as 64 cubic meters.

2. Understand how scaling affects the volume:
When a three-dimensional object, such as a cube, is scaled by a factor, the volume changes by the cube of that scaling factor.

3. Calculate the new volume:
Since the scaling factor is 5, the volume of the cube after scaling will be:
[tex]\[ \text{New Volume} = \text{Original Volume} \times (\text{Scaling Factor})^3 \][/tex]
Plug in the values:
[tex]\[ \text{New Volume} = 64 \times 5^3 \][/tex]
Calculate [tex]\( 5^3 \)[/tex]:
[tex]\[ 5^3 = 5 \times 5 \times 5 = 125 \][/tex]
Then the new volume will be:
[tex]\[ \text{New Volume} = 64 \times 125 \][/tex]

4. Multiply to find the final answer:
[tex]\[ 64 \times 125 = 8000 \][/tex]

So, the volume of the modified cube is [tex]\( \boxed{8000} \)[/tex].
