` = "Pyramid Roof Geometries"`

Enter a value for all fields

The **Pyramid Specifications** calculator computes the metrics associated with of square based pyramid.

**INSTRUCTIONS**: Choose units and enter the following:

- (
**L**) Length of Base Sides - (
**P**) Pitch

**Pyramid Specifications (PS):** The calculator returns:

- (
**V**) Volume in cubic feet. - (
**TSA**) Total Surface Area in square feet. - (
**FA**) Surface Area of one Face - (
**BA**) Base Area in square feet - (
**BD**) Base Diagonal in feet - (
**α**) Angle of Face corners - (
**i**) Face Length in feet - (
**j**) Hip Ridge Length in feet - (
**HRL**) Total Hip Ridge Length in feet - (
**ALL**) Returns all the above

**Note**: answers can be automatically converted to compatible units via the pull-down menu.

Based on the input parameters and the assumption of a square base, this calculator makes the following calculations:

- y = L/2
- h = tan(Θ) * y
- z = sqrt(2*y
^{2}) - j = sqrt(z
^{2}+ h^{2}) - i = sqrt(y
^{2}+ h^{2}) - α = asin(i/j)
- FA = y*i
- TSA = FA*4
- HRL = j*4
- BA = L*L
- BD = sqrt(L
^{2}+ L^{2})
