Answer 7

Do you want to visualize this prism?

Answer 8

i dont unnderstand this

Answer 9

Do you understand what surface area is?

Answer 10

What is the surface area of this prism if the height of the prism is 11 meters?

Answer 11

Surface area is the same as regular area just extended to a 3 dimensional object.

Answer 12

In this case you have 5 surface areas to calculate and then add up to give the total surface area.

Answer 13

Are you familiar with the formula to calculate the area of a rectangle?

Answer 14

@tj_1502

The surface area of the prism can be found by the following formula:

SA = p*h + 2*B where p is the perimeter of the base and B is the area of the base.

SA = (15+9+12)*11 + 2*(1/2)*9*12

SA = ?

Answer 15

Directrix can you help me please

Answer 16

So you don't want my help?

Answer 17

i just dont get anything your trying to tell me

ok

Answer 20

Do you know the definition of area?

Answer 21

yes

Answer 22

What is it?

Answer 23

@tj_1502

SA = (15+9+12)*11 + 2*(1/2)*9*12
SA = 36*11 + 9*12
SA = ?
