an open storage box is shaped like a square prism but without a top face. the base of the box is a square with side length 12 in., and the height of the box is 10 in. what is the surface area of the box?

a.) 600 square inches

b.) 624 square inches

c.) 768 square inches

d.) 1,440 square inches

braden chose c as the answer. why is his answer incorrect?

Braden is incorrect because the correct answer is B. He included the top face of the box

Step-by-step explanation:

To find surface area, just add up the areas of all of the sides of the shape. In this case, you would have one side with 144 in^2 (12 * 12) and four sides with 120 in^2 (10 * 12). Add these together and you get 624

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
