Question

please help

Answer 1

V = 1/2 (5*3*8.5)

Answer 2

So the equation for this is \(V=\dfrac{1}{2}bah\)

so we must find the area before we can find the volume, which is:
\(A=\dfrac{1}{2}bh\)

so \(A=\dfrac{1}{2}(5\times8.5)\)

find the area and then continue on,

finding the volume of a triangular prism would be this:
\(V=\dfrac{1}{2}(5)(a)(8.5)\)

Answer 3

\(a\) being the Area of the triangular prism.

Answer 4

ok what do i write in the box as my answer

Answer 5

exactly, but to find the volume in this question, you need to find the area

Answer 6

so you can do \(V=\dfrac{1}{2}bah\)

Answer 7

what's thev0lume

Answer 8

Where did both of you get your formulas from?

Answer 9

that's the way i was taught to solve a question like this

Answer 10

It's a rectangular pyramid...

\(\text{Volume of rectangular pyramid}= \dfrac{1}{3} \times \text{Length} \times \text{Width} \times \text{Height}\)


and the base length is 5 inches
the base width is 3 inches

and the height is 8.5 inches

so what is the volume?

Answer 11

thank you az

Answer 12

What do you get as your final answer?

Just multiply the 3 numbers and then divide by 3

Answer 13

ohhhh, but wouldnt this be considered a square-based pyramid, so \(V=a^2\dfrac{h}{3}\)?

Answer 14

The base is 5 by 3

so it's a rectangle not a square

Answer 15

ah, ok, thanks AZ

Answer 16

42.5

Answer 17

no problem :)

Answer 18

just more equations to add to my list of equations....
