Question

find the volume

Answer 1

Ab is area of the base, which is an equilateral triangle with each side 8cm.
Do you know how to find the area of an equilateral triangle?

Answer 2

isnt it like 3/4 s^2

Answer 3

would it be 3.5 than?

Answer 4

correction:
=s*2s sqrt(3

Answer 5

So area of triangle
= sqrt(3) s/2 * s/2
=sqrt(3) s/4

Answer 6

* sqrt(3) s^2/4

Answer 7

what does that give you for Ab?

Answer 8

i don't understand what to do for s^2/4

Answer 9

s=8 cm = side of triangle.
you multiply sqrt(3) by 8^2/4

Answer 10

3.5?

Answer 11

8^2=64
8^2/4=16
Multiply that by sqrt(3) gives ?

Answer 12

27.7

Answer 13

@Jaynator495
Now you need to find the height of the prism from the diagram, can you do that?

@Jaynator495 Sorry, wrong tag, please ignore.

Answer 15

would the height be 19? @mathmate

Answer 16

Yes, the height is 19 cm. (don't forget the units)

Answer 17

what do i do for the volume then? @mathmate

Answer 18

The volume is obtained by multiplying the area of the base (Ab) and the height.
You can use the calculator for that.

Answer 19

526.3/ @mathmate

Answer 20

I have 526.54 if you use more accurate numbers for sqrt(3), such as 1.7321 (instead of just 1.73).
Good job.

Answer 21

You done goofed mathmate x'D
