Question

How many 3/4centimeter cubes do you need to create a cube with an edge length of 12 centimeters?

Answer 1

Answer:

16

Step-by-step explanation:

12 ÷ 3/4 = 16

Answer 2

Answer:

• Minor note: All side lengths of a cube are the same.
• Also, formula for a cube or rectangular prism is; L x W x H

Find the volume of the big cube with a side length of 12;

12 x 12 x 12

= 1,728 cm3 is the total volume for the big cube.

Now, let's find the volume of the small cube with a side length of 3/4;

3/4 x 3/4 x 3/4

= 27/64 cm3 is the total volume for the small cube.

To see how many of these small cubes are needed to fit the larger cube, we must divide the larger cube's volume by the smaller cube's volume:-

1,728÷ 27/64

= 4,096 are needed of the small cubes to fit the larger cube.
