Clare is using little wooden cubes with edge length 1/2 inch to build a larger cube that has edge length 4 inches. How many little cubes does she need? explain your reasoning

Clare will need 8 little cubes of 1/2 edge length to build a larger cube that has 4 inches of edge length.

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Little wooden cubes edge length = 1/2 inch

Larger cube edge length = 4 inches.

2. How many little cubes does Clare need to build the larger cube?

We can calculate the number this way:

Number of little cubes for building a larger cube = 4/0.5 (1/2 = 0.5)

Number of little cubes for building a larger cube = 8

Clare will need 8 little cubes of 1/2 edge length to build a larger cube that has 4 inches of edge length.
