Question

lesson check (5.nbt.7)

1. write a division sentence that tells what the model represents.

Explanation:

Step1: Calculate total cubes

Each large cube (10x10x1) has \(10\times10 = 100\) cubes. There are 2 large cubes: \(2\times100 = 200\). Each long row (10 cubes) has 10 cubes, 2 rows: \(2\times10 = 20\). Single cubes: 2 + 2 = 4. Total: \(200 + 20 + 4 = 224\).

Step2: Determine division context

Assume dividing by 2 (since two sets of each model). So division sentence: \(224\div2 = 112\).

Answer:

\(224\div2 = 112\)
