Quadrilateral prism

A regular quadrangular prism is a geometric figure whose base is a square.
Formula for the surface area of a quadrangular prism Formula for the surface area of a quadrangular prism where a is the side of the base, h is the height of the prism

Solution:
S = 2·a2 + 4·a·h
= 2·52 + 4·5·2
= 2·25+40
=
90

a: The area of the entire surface of a quadrangular prism with the base side a = 5 and height h = 2 equal to 90
