2)
if the template is 3mm think, what is the volume in cubic millimetres?
do i split it into 2 rectangles, triangle & a circle?

area of circle 3.141 * 25 squared = 1963.125cm2
area of rectangles = Length * Width or Base * Height
220mm * 30mm = 6600mm2 or 66cm2
130mm * 30mm = 3900mm2 or 39cm2
area of triangle = 1/2 * base * height
1/2*130mm*125mm=8125mm2
how do i find out the volume in cubic millimetres if the template is 3mm thick?
