Question

Can someone please explain to me how to find Total area and Lateral area of a prism? I do not understand how to use these when finding my answers.

Answer 1

a prism has sides, and bases .... total area is all of it, and lateral is a word that means sides.

Answer 2

lateral + bases = total area

total - bases = lateral

Answer 3

Thank you and how could i use that to find the T.A. of this shape?

Answer 4

2 bases, and 3 sides ... what are your thoughts?

Answer 5

These are formulas i have been given with my work:
Lateral area= ph
Total area= ph+2b

Im not really certain on how i can find the perimeter, that is the part that confuses me.

Answer 6

perimeter is the perimeter of a base ... perimeter is the sum of the sides of the base

Answer 7

how do we find the 3rd sides of a right triangle?

Answer 8

visually that off, 6 should be bigger than 4 ... but it still works the same

Answer 9

Im sorry but im not sure how..I am not very smart at this.

Answer 10

one of the basic formulas you learn deals with right triangles and the relationship of their sides. something pythagorean

Answer 11

its a formula that never goes away in math ... youll use it almost everywhere so you bet put it to memory

a^2 + b^2 = c^2

Answer 12

Oh okay, so would i do 4^2+6^2 to equal my answer..?

Answer 13

close

4^2 + 6^2 = c^2 but we just want c, take the square roots

sqrt(16+36) = c

Answer 14

oh okay that makes more sense. So in finding that i have perimeter right? than just multiply that by height?

Answer 15

yep

perimeter of base is: 4+6+sqrt(52) = 10+2sqrt(13)

Answer 16

Okay how would i use than with total area then?

Answer 17

well you know the side area is ph

and the base areas ... what is the area of a triangle?

Answer 18

How would I find out the area? I'm sorry but as i have said before I am not very good with things like this.
