The area of any regular polygon can be expressed as:
(ns^2)/(4tan(180/n)) where n is number of sides and s is a side length (no apothem needed :D)
37.2=5s^2/(4tan36)
s^2=(148.8tan36)/5
s≈4.65m
The real cube root is 0.03 because...
(0.000027)^1/3 = (27 x 10^-6)^1/3 = 3 x 10^-2 = 0.03
Martin will have to mark 0.125 on the
Let the original weight of the scale be 1kg. Hence we can say the original mark for 1kg weight is 1 that is:
1kg = 1 ................ 1
Since we are to calculate where to mark for a 1/8 kg weight, we can write;
1/8 kg = x ..................2
Divide both expressions

This means Martin will have to mark 0.125 on the scale.
