Answer 1

To find the total surface area, first we need to find the area of each side of the prism.

Answer 2

We'll start with the front side. The length is 13m and the height is 5m. Can you find the area from that?

Answer 3

Remember area = length x width

Answer 4

65

Answer 5

Great! And since there's two faces on the prism with those dimensions, we'll multiply that by 2. So, 65 x 2 = 130.

Can you repeat that process for the other faces of the prism?

Answer 6

Probably not. Lol.

Answer 7

area = length x width
We've already found the area for two faces of the prism, so we need to do the other two now.
6 x 5 x 2 = ?
13 x 6 x 2 = ?

Answer 8

Can you solve those two equations?

Answer 9

6x5x2=60
13x6x2 = 156

Answer 10

Good. So our areas so far are 130m^2, 60m^2, and 156m^2. What do you think we should do next?

Answer 11

add them together?

Answer 12

Yep!

Answer 13

So 130 + 60 + 156 = ?

Answer 14

346 (sorry if I posted this twice it lagged up when I posted)

Answer 15

Correct! And that's fine :) So the answer is 346m^2 (don't forget the label!)

Answer 16

Thank you. The Lizard on my head also thanks you >.> lol

Answer 17

Lol no problem!
