Scalene Triangle Slab Concrete Volume

Calculator For Scalene Triangle Spike VM

The Scalene Triangle Volume Calculator - Imperial helps you calculate the concrete volume required for a slab shaped like a scalene triangle. This calculator uses three side lengths (Side A, Side B, Side C) and a specified depth to determine the area, perimeter, and volume in cubic feet, cubic yards, and cubic metres.


Scalene Triangle Concrete Calculator

Side A Length:   ft  in.
Side B Length:   ft  in.
Side C Length:   ft  in.
Depth:   in.
Area:   ft ²
Perimeter:   lin ft

Amount of concrete needed:

Cubic Feet:   ft ³
Cubic Yards:   yd ³
Cubic Meters:   m ³

Calculator

  1. enter the length of side A in feet
  2. the length of side B in feet
  3. the length of side C in feet
  4. the slab thickness (depth) in inches

Results

  1. the area of the slab in square feet
  2. the perimeter of the slab in lineal feet for forming material
  3. the amount of concrete needed in cubic feet
  4. concrete needed in cubic yards
  5. required concrete in cubic metres

Conversions
one cubic foot (ft³)= 0.037037037037037 cubic yards (yd³)
one cubic foot (ft³) = 0.028316846592 cubic metres (m³)
Formula and Example Calculation
Side A = 5 feet
Side B = 6 feet
Side C = 7 feet
Depth = 8 inches
Area of a Scalene Triangle (using Heron's formula):
Calculate the Semi-Perimeter:
s = (A + B + C) / 2
s = (5 + 6 + 7) ÷ 2 = 9
s is the semi-perimeter.
Area = s * (s - A) * (s - B) * (s - C)
where:
A, B, and C are the lengths of the sides of the triangle.
Area = √9 * (9 - 5) * (9 - 6) * (9 - 7)
Area = √9 * 4 * 3 * 2
Area = √216 = 14.6969 square feet
The Perimeter of a Triangle:
Perimeter = A + B + C
Perimeter = 5 + 6 + 7 = 18 feet
Calculate the Volume of Concrete Needed:
The volume V of concrete is the area multiplied by the depth (converted to feet):
V = A * depth in feet
Convert depth from inches to feet:
Depth (feet) = 8 ÷ 12 = 0.66666 feet
14.6969 * 0.66666 = 9.7979 cubic feet
9.7979 * 0.037037037037037 = 0.3628 cubic yards
9.7979 * 0.028316846592 = 0.2774 cubic metres
Results
Area: 14.7 square feet
Perimeter: 18 feet
Volume: 9.8 cubic feet
Cubic Yards: 0.36 cubic yards
Cubic Meters: 0.2775 cubic meters

This tool simplifies estimating the concrete volume needed for scalene triangle slabs in construction projects. Accurate input values will ensure reliable results for planning and material estimation.


When Ordering Concrete

This concrete calculator will help you in estimating the amount of concrete needed for your project. The amount given as needed, does not include any waste. It is recommended, depending on the job you are doing, to add anywhere from an extra 4% to 10% to your concrete order to make sure you have enough concrete to finish the job. Ask when ordering the concrete. They will be able to give you a good idea of what is needed.
