What is the surface area of a square prism with a base side length of 9 cm and a slant height of 7cm.
1 answer:
Answer:
414cm^2
Step-by-step 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
