The area of the prism is 420 in. You just have to add 144 + 90 + 90 + 48 + 48 which is equal to 420 in². You just had to add the sides

Hope it helps :)

If you want to find the surface area of something and it doesn't have a formula, just look at the area of each side individually and add them up!

The area of a triangle is equal to bh/2 = 16*6/2 = 48 in²
The area of the other triangle would be the same = 48 in²
The lateral side that's 10 by 9 inches = 10 * 9 = 90 in²
The other lateral side that's 10 by 9 is also = 90 in²
The lateral side that's 16 by 9 inches = 16 * 9 = 144 in²

144 + 90 + 90 + 48 + 48 = 420 in²

Answer:

They are not diffrent at all. may look diffrent from the question but lets look a little closer!

Step-by-step explanation:

2-3=1 and 3-2=1 both answers look the same because the equion is Both 3s in 3-2 and 2-3 looks no diffrent. To be honest one is only backwords from the other one! But remeber to think BIG and look at those diffrentses.
