Question

What is the surface area of a square prism with a base side length of 9 cm and a slant height of 7cm.

Answer 1

414cm^2

Explanation:

Given data

Base a= 9cm

Hence the expression for the surface area is

SA=2a^2+4ah

A=2*9^2+4*9*7

A=162+252

A=414cm^2

Hence the surface area is 414cm^2
