How do you find the surface area for this???
Katarina [22]
The surface area of any object is the sum of the areas of all the faces. In this case, we have a rectangular prism with dimensions 8x4x3 and a trianglar prism with a 8x4 rectangular base and height of 6.

Let's start with the rectangular prism. We have the bottom which is 8x4, two sides that are 3x4, and two sides that are 8x3.

8*4 + 2*3*4 + 2*8*3 = 104 in^2

Now that's find the surface area of the trianglar prism. We have the rectangular side on top which is 10x4, the rectangular side on the right which is 6x4, and two triangles that are 8 long and 6 high.

10*4 + 6*4 + 2*0.5*8*6 = 112 in^2

The total surface area is 104 + 112 = 216 in^2

Simplifly the expression 5^0
Angelina_Jolie [31]

ANY number raised to the zero power is ' 1 '.

your friends, especially the ones who don't know
how to do it without running to Google.)

So  5^0  =  1 .

Tamara and Amir shared a candy bar. Tamara ate two fifths. Amir ate two fifths. How much is left?
marin [14]

Answer:

1/5

Step-by-step explanation:

Both Amir and Tamara ate 2/5 each.

2/5 + 2/5 = 4/5

If 4/5 of the candy bar was eaten, 1/5 of the candy bar remains because

5/5 - 4/5 = 1/5

(Remember that 5/5 just equals one whole, representing the whole candy bar)
