You have a square prism with a height of 9cm and a base area of 36cm 2. What is the total surface area of the prism?

288

Explanation:

Since this is a cube, all sides are equal

If you you will get an answer of 6. This is the length of the sides of your square prism.

Now that you know your "a" value

you find your "h value, which is already given.

h= 9cm

a= 6cm

There are two faces which equal 36

36+36= 72

There are 6 faces to a prism and you know two so you have 4 left

9(6)= 54

54(4) = 216

Now you have all your numbers for surface area, so you add them up

215+72 = 288

Hope that helps (:

Would appreciate if you rated my answer as well (:
