Answer 1

Common formula: 1/3 * area of hexagon * height.

Answer 2

Total area = total surface area?

Answer 3

Yes.

Answer 4

ok so in diagram 6 is the length along the edge correct? so the total area is (1/2)(4*6)* 6 + area of hexagon

Answer 5

area of each triangle is 1/2 B*H and there are 6 sides

Answer 6

so total area is 72 + area of the hexagon base

Answer 7

the hexagon base made of 6 equilateral triangles of sides with 4
the area of the equilateral triangle is 1/2 b*h
to find the height we find
this is a 30.60,90 triangle where the height is 2*sqrt(3)
