## General formulas and calculations

Surface

Rectangle: length x width
Circle: pi x r x r
Triangle: (height x basis)/2

Volume

Rectangular ba: length x width x height
Tube: pi x r x r length
Piramyd: (basis x height)/3

Perimeter

Circle: pi x diameter

Inhoud

1 liter = 1000 ml. = 1 dm3
A square box of 100 x 100 x 100 cm has a volume of 1.000.000 cm3 = 1.000 dm3 = 1 m3

Weight

Weight: volume x density
Density: weight/volume
Volume: weight/density

## Handy formulas area calculation of ships

Below some handy formulas:

Underwater ship for a non deep stabbing (sailing)boat:
Surface area in m2 = 0,5 x length of the waterline x (width + depth)

Underwater ship for a deep stabbing sailboat:
Surface area in m2 = 0,75 x length of the waterline x (width + depth)

Surface ship:
Surface ship in m2 = (Length over all x width) x 2 x height waterline till deck

Surface area of the deck:
Surface area in m2 = (0,75 x Length over all x width) minus surface area of construction

## Remove cured epoxy

Heat the epoxy with a hair dryer upto a maximum of 90 degrees Celcius untill the epoxy gets soft again. Remove epoxy as much as possible with a scraper or putty knife. The remaining epoxy can be removed with sanding paper. Provide for enough ventilation when heating epoxy.

## Releasing epoxy

Epoxy sticks to virtually anything but not to polyethylene. Garbage bags are made of that. Handy when you want to coat something but afterwards be able to remove your project from the underlay.

To make a ledge which later can be removed.

We also sell mold release wax. With this wax you treat a mold so that it can be released from the project afterwards.

## Removing non cured epoxy

This works excellent with white wine vinegar. Much healthier than the chemical substances. Available and sold in any supermarket.

## Extend cure time

After mixing poor the epoxy from a mixing cup into a paint tray. The epoxy is spread over a larger area and can be used longer. Also a lower temperature gives you more time to apply the epoxy.

## To make epoxy glue or putty in wood colour

To finish unpainted wood, you might want to keep the original wood colour. Mix the epoxy with saw dust untill the desired thickness and finish the wood with this mix.
