Answer:
224 cubes
Step-by-step explanation:
1. Find the area: 2 * 1 *7/4 = <em>7/2 cm³</em>
2. Find how many cubes fit into 1 cm³: 4 * 4 * 4 = <em>64 cubes</em>.
3. Multiply the two numbers: 7/2 * 64 = 224 cubes.
Answer:27.5%
Step-by-step explanation:
4000-2900=1100
1100÷4000=27.5%
Answer: 20 meters.
Step-by-step explanation:
The formula for calculate the area of a square is:

Where "s" is the side length of the square:
The formula for calculate the area of a rectangle is:

Where "l" is the lenght and "w" is the width.
Based on the information provided, you know the sum of the areas of the square land and the adjacent land is 600 m². This is:

Knowing that the width of the adjacent land is 10 meters:

Since the lenght of the adjacent land and the side lenght of his actual land are equal:

You can substitute this into
:

Applying the Quadratic formula, you get:

Since the side lenght cannot be negative, you can determine that this is:
