Understanding the Formulas
The calculator is based on fundamental geometry formulas. Let’s break them down:
1. Area Formula
A=l×w
Explanation:
Area represents the surface covered by a shape. For a rectangle, multiply length by width.
2. Volume Formula
V=l×w×h
Explanation:
Volume measures the space inside a 3D object. Multiply length, width, and height.
3. Perimeter Formula
P=2(l+w)
Explanation:
Perimeter is the total distance around a rectangle.
Example Calculations
Example 1: Basic Rectangle
- Length = 10 m
- Width = 5 m
- Height = 2 m
Results:
- Area = 10 × 5 = 50 m²
- Volume = 10 × 5 × 2 = 100 m³
- Perimeter = 2(10 + 5) = 30 m
Example 2: Small Object
- Length = 4 cm
- Width = 3 cm
- Height = 2 cm
Results:
- Area = 12 cm²
- Volume = 24 cm³
- Perimeter = 14 cm
Measurement Table Examples
| Length | Width | Height | Area | Volume | Perimeter |
|---|---|---|---|---|---|
| 10 m | 5 m | 2 m | 50 | 100 | 30 |
| 8 ft | 6 ft | 3 ft | 48 | 144 | 28 |
| 12 in | 10 in | 5 in | 120 | 600 | 44 |
| 4 cm | 3 cm | 2 cm | 12 | 24 | 14 |
| 15 m | 10 m | 4 m | 150 | 600 | 50 |
Unit Conversion Insights
Although the calculator allows different units, understanding conversions can be helpful:
| Unit Type | Conversion |
|---|---|
| 1 meter | 100 cm |
| 1 foot | 12 inches |
| 1 inch | 2.54 cm |
| 1 meter | 3.28 feet |
