lilcutie2:

I can try and help

Tonycoolkid21:

sure

Honda:

do you remember how to find lateral surface area?

Angle:

lateral surface area is the surface area of the shape that does not include the base in this case, it's just all of the rectangles

Tonycoolkid21:

ok so what do i do

Angle:

what's the area of the rectangle in your picture?

Tonycoolkid21:

A=bh

Angle:

ok, so what's the area of the rectangle in your picture?

Angle:

multiply the two numbers that are on the sides of the rectangles

Tonycoolkid21:

4 x 4

Angle:

try again

Tonycoolkid21:

6 x 4

Angle:

good!

Angle:

then you have three of those rectangles

Tonycoolkid21:

6 x 4 =24

Angle:

ok then times 3 to get your answer

Tonycoolkid21:

72

Angle:

that is your lateral surface area answer

Angle:

then to find the total surface area... what's the area of this triangle?

Tonycoolkid21:

3 and 4

Angle:

h=3 b=4 A = b h / 2

Tonycoolkid21:

12 x 0.5 divide my 2

Angle:

what do you get?

Tonycoolkid21:

3

Angle:

12 divided by 2 = 6

Tonycoolkid21:

k

Angle:

multiply that by how many triangles you have

Tonycoolkid21:

18

Angle:

you only have two triangles in your picture

Tonycoolkid21:

12

Angle:
