A regular triangular prism is a geometric figure whose base is an equilateral triangle.
Triangular prism surface area formula
where a is the side of the base, h is the height of the prism
A regular quadrangular prism is a geometric figure whose base is a square.
Formula for the surface area of a quadrangular prism
where a is the side of the base, h is the height of the prism
A regular hexagonal prism is a geometric figure whose base is a regular hexagon.
Hexagonal prism surface area formula
where a is the side of the base, h is the height of the prism
Solution:
S = 2·a2 + 4·a·h
= 2·152 + 4·15·20
= 2·225+1200
=
1650
a: The area of the entire surface of a quadrangular prism with the base side a = 15 and height h = 20 equal to 1650
