Find the surface area of the following triangular prism.

144 ft squared

Step-by-step explanation:

Let's find the two bases first. They are triangles with a base of 6 and a height of 8. The formula for the area of a triangle is b * h *  1/2 = 6 * 8 * 1/2 = 24. There are two so you would do 24 * 2 which is 48.

Then let's find the area of the other three faces, all of which have a length of 4. One has a width of 8 so you would do 4 * 8 which is 32. Another has a width of 6 so you would do 4 * 6 which is 24. The last one has a width of 10 so you would do 4 * 10 which is 40.

Add up the areas of the two bases and three faces together:

48 + 32 + 24 + 40 = 144 ft squared

Hope this helped!

won't that be plagrisim thought?

step-by-step explanation:

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
