Wedge Surface Area Calculator
Formulas Used:
Slanted Edge = √(h² + ((base − top)/2)²)
Slanted Face = Width × Slanted Edge
Total Area = Sum of all face areas
A wedge is a simple but very useful shape found in many everyday tools and engineering designs. Doorstops, axes, ramps, chisels, and many machine parts all use a wedge shape. Even though it looks simple, calculating the area of a wedge can be confusing if you don’t know the right formulas.
The Wedge Area Calculator makes this task easy. By entering a few basic measurements, you can quickly find the triangular face area, surface area, or even the volume of a wedge. This is helpful for students, builders, engineers, designers, and DIY users.
What the Wedge Area Calculator Is
A Geometry-Based Measurement Tool
The Wedge Area Calculator is an online tool that helps you calculate the area of a wedge-shaped object. A wedge can be understood as a triangular prism, where the front and back faces are triangles, and the sides are rectangles.
The calculator typically finds:
- The triangular face area
- The surface area of the wedge
- Sometimes the volume of the wedge
Why Wedge Area Matters
Knowing the area of a wedge helps with:
- Material estimation
- Tool design
- Structural planning
- School geometry problems
- Surface coating or painting
Accurate area calculations help save time, money, and materials.
How the Calculator Works
Step 1: Enter the Base
The base is the bottom side of the triangular face of the wedge.
Step 2: Enter the Height
The height is the perpendicular distance from the base to the top point of the triangle.
Step 3: Enter the Width
The width (or depth) is how long the wedge extends backward.
Step 4: Get the Results
The calculator uses standard geometry formulas to show the wedge’s area instantly.
Key Formulas Used
Triangular Face Area
Face Area = (Base × Height) ÷ 2
This gives the area of the triangular front face.
Wedge Volume
Volume = Face Area × Width
This treats the wedge as a triangular prism.
Surface Area of a Wedge
Surface Area = 2 × Face Area + (Perimeter of Triangle × Width)
This includes the front, back, and side surfaces.
Step-by-Step Example
Example: Simple Wedge
Given:
- Base = 10 cm
- Height = 6 cm
- Width = 5 cm
Step 1: Find triangular face area
Face Area = (10 × 6) ÷ 2 = 30 cm²
Step 2: Find volume
Volume = 30 × 5 = 150 cm³
Step 3: Find surface area (approximate)
Perimeter of triangle ≈ 10 + 6 + 11.66 = 27.66 cm
Surface Area = 2 × 30 + (27.66 × 5)
Surface Area = 60 + 138.3 = 198.3 cm²
