# The area of the entire surface of a quadrangular prism with the base side a = 15 and height h = 20 equal to 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

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

Solution:

S = 2·a^{2} + 4·a·h

= 2·15^{2} + 4·15·20

= 2·225+1200

=

1650
