The volume of the pyramid is 2496 cu.m.
<h3>What is a Pyramid ?</h3>
A pyramid is a three dimensional structure which has a polygon base and in general triangular faces which join at the top .
It is given that
A pyramid 
has a 4 m by 4 m square top
Height = 12 m
Base = 20 m
The volume of a square pyramid with a is given by
V = (1/2) * ( Area of base + Area of ) * height of the from the base
V = 0.5 * ( 20 *20 + 4*4 ) * 12
V = 2496 cu.m
The volume of the pyramid is 2496 cu.m.

Women are = 3/5
So, Men Must be = 2/5
Ratio of Men to Women:

8% of 20 is 1.6
This is because you take the percentage and divide it by 100 so that you have a decimal, then multiply that by twenty. So, 8% ÷ 100 = 0.08 then 0.08 × 20 = 1.6
