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

30 POINTS FOR THE GENUIS WHO CAN ANSWER THIS!!
bearhunter [10]

Answer:

Answers are below in bold

Step-by-step explanation:

1) A = 1/2bh          Use this equation to find the area of each triangular base

A = 1/2(8)(6)         Multiply

A = 1/2(48)           Multiply

A = 12cm²           Area of each triangular base

2) A = L x W        Use this equation to find the area of the bottom rectangular face

A = 20 x 8          Multiply

A = 160 cm²       Area of the bottom rectangular face

3) A = L x W        Use this equation to find the area of the back rectangular face

A = 20 x 6          Multiply

A = 120 cm²       Area of the back rectangular face

4) A = L x W        Use this equation to find the area of the sloped rectangular face

A = 20 x 10         Multiply

A = 200 cm²      Area of the sloped rectangular face

5) To find the total surface area of the triangular prism, add together all of the numbers.

A = 12 + 12 + 160 + 120 + 200       Add

A = 504 cm²       Total area of the triangular prism
