Could I help you?

pokiedokie · Answer

so i just plug in the numbers then?

pokiedokie · Answer

isn't it a lot different from a triangular prism though??

3mar · Answer

This depends on the basis of your prism, as the lateral area is the total surface area except the areas of the two basis of the prism.

3mar · Answer

Not so different:
- the surface area is the sum of areas of all faces (5 faces in case of triangular prism).
- the lateral area is the surface area except the areas of the two basis of the prism (3 rectangular faces in our case here).

- The lateral area = sum of the (yellow+pink+green outlined) area
- The surface area = the lateral area + the areas of orange triangles
