you dont learn it ?

Answer 12

The formula for the volume of a prism is V=Bh

Answer 13

B what is ?

Answer 14

how you calcule the B ?

Answer 15

base
and h id hight

Answer 16

B not is base

B is area of base

Answer 17

oh

Answer 18

but then you see the base triangle is a right triangle so you can calcule easy area of this triangle - yes ?

Answer 19

im lost

Answer 20

this is the base triangle

area of this triangle = ?

Answer 21

\(\color{#0cbb34}{\text{Originally Posted by}}\) @jhonyy9
A = base *height /2

A = ?

Answer 22

6

Answer 23

yes so area of base you now equal 6

volume equal area of base time height

Answer 24

the height of prism = ?

Answer 25

h = 7 yrd

Answer 26

V = B *h

V = ?

Answer 27

idk jeeez u make it so hard\

Answer 28

V = B*h

B = 6 yrd^2
h=7 yrd

V = ?

Answer 29

V = 6*7 = ? yrd^3

Answer 30

ok ?

Answer 31

its 42

Answer 32

\(\color{#0cbb34}{\text{Originally Posted by}}\) @narutouzamaki2
its 42
\(\color{#0cbb34}{\text{End of Quote}}\)
yes ofc 42 yrd^3

Answer 33

now az]
can u help me with the rest

Answer 34

rest of what ?

Answer 35

I'm sorry that you're still confused.

Let me try to explain.
You know that area is trying to find the area for a 2-Dimensional object like a circle or a square.

Volume is trying to find the area for a 3-Dimensional object like a cylinder or a prism.

When you think of the concept of volume, it's basically like trying to find how much water you could pour into that container.
When you're finding the area of a rectangle, it's like trying to find how much paint you would need to paint that wall.

What makes volume different from area is the height aspect. You just multiply the area of the base by the height.

That's how Jhonny got
Volume = area of the base * height

Does that help clarify things?
