Pentagon Shaped Slab Concrete Volume

Calculator For Pentagons Spike VM

The Pentagon Shaped Slab Concrete Volume Calculator efficiently calculates the concrete needed for a pentagon-shaped slab. This calculator requires the length of a side (in feet and inches) and the pentagon slab's depth (in inches) as inputs. It calculates and displays results for the area in square feet, perimeter in linear feet, and the total concrete volume in cubic feet, cubic yards, and cubic metres.


Pentagon Shaped Volume Calculator - Imperial

Length of Side:   ft  in.
Depth:   in.

Amount of concrete needed:

Area:   ft ²
Perimeter:   l.ft
Cubic Feet:   ft ³
Cubic Yards:   yd ³
Cubic Meters:   m ³

Calculator

  1. enter the length of one side in feet
  2. slab thickness in inches

Results

  1. the area of the slab in square feet
  2. the perimeter of the slab in lineal feet
  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)
Example Calculation
Side length, s = 4 feet
Depth, d = 6 inches
Calculate the Area:
Using the formula:
Area = 5/4 * 4² * cot(π / 5)
Area = 1.25 * 16 * 1.376381920471174 = 27.5276 feet
Calculate the Perimeter
Perimeter = 5 * s
Perimeter = 5 * 4 = 20 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) = 6 ÷ 12 = 0.5 feet
Calculate the volume:
V = 27.5276 * 0.5 = 13.7638 cubic feet
13.7638 * 0.037037037037037 = 0.5098 cubic yards
13.7638 * 0.028316846592 = 0.3897 cubic metres
Results
Area: 27.528 square feet
Perimeter: 20 feet
Concrete Volume:
13.764 cubic feet
0.51 cubic yards
0.39 cubic metres

This tool helps estimate the required concrete volume for pentagon-shaped slabs, aiding in construction 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.
