Answer 1

350.82

Explanation:

To find the surface area, you must add up all of the areas of each shape of the prism in order to get the sum surface area.

The rectangle's area (
`lw`):

`7.21*14=100.94`

The triangle's area (
`(1)/(2)bh`):

`(1)/(2) (6)(8)`

`(1)/(2) (48)=24`

Now add up all the sides. (3 Rectangles, 2 Triangles.)

`100.94 + 100.94 + 100.94 + 24 + 24`

`=350.82`

The total surface area is 350.82 cm squared.
