Answer:

Hello! answer: 268

Step-by-step explanation:

When doing these you want to find each face separately then add them up so here are all the faces... 24 + 24 + 80 + 80 + 30 + 30 = 268 so 268 is our surface area! Hope this helps!

Answer:

268 cm²

Step-by-step explanation:

Surface area: The sum of all the areas of every side of the prism.

As a shortcut, you can find the three unique sides and multiply the number by 2 (because opposite sides of a rectangular prism are the same)

Find the surface area of:

8 by 10 side: 8 * 10 = 80

3 by 8 side: 3 * 8 = 24

3 by 10 side: 3 * 10 = 30

Add these measures together.

80 + 24 + 30 = 134

Multiply this number by 134.

134 * 2 = 268

Thus, the answer is 268 cm²
