Question

How many 1-inch cubes do you need to create a cube with an edge length of 5 inches?

Answer 1

Answer:

125

Step-by-step explanation:

We have to find that How many 1-inch cubes do you need to create a cube with an edge length of 5 inches.

Now, $Volume of one inch cube=1{\times}1{\times}1=1 cubic inches$

and $Volume of five inch cube=5{\times}5{\times}5=125 cubic inches$.

Therefore, $Number of 1 inch cubes=\frac{volume of 5inch cubes}{volume of one inch cube}$

=$\frac{125}{1}$

=$125$

Therefore, we need 125 one inch cubes to create a cube with an edge length of 5 inches.

Answer 2

Number of 1 inch cubes:

Volume of the 1 inch cubes = 1*1*1 = 1 cubic inches.

Volume of the 5 inch cubes =  5*5*5 = 125 cubic inches.

Number =  Volume of the 5 inch cubes / Volume of the 1 inch cubes

            =  125 /1 = 125.

125 of the 1-inch cubes.
