1. ## How the **** do i figure out the volume of a triangle

Obviously i fail at math but im trying to figure out the volume of this triangle-ish box im working on designing. I think im going in the wrong direction here but i need about 7 cubes net, and a box no taller than 15 inches, has to be slant face as the subs are 15.5 inches wide. Im gonna attempt to do this myself but im having trouble planning everything out before i get the materials

Heres my max specs. I could go bigger but i wanna leave a little airspace around the box too.

15.5 inches tall
18 inches deep
55 inches wide (this is pushing the limits of my trunk, i have 60 inches of width in total, at the trunk opening)

heres what i got so far

add top and bottom depth and divide by 2, thats the length of the depth

separate that into a triangle and a rectangle. for the triangle its (1/2)(base)(height)(length) and then for the rectangle its just (H)(W)(L)

4. ## Re: How the **** do i figure out the volume of a triangle

Measure the depth and the 1/2 the height use that as your "D" in ( L * W * D/1728) and there is your answer

If all else fails, build it, and fill it with packing materials.

Then empty the packing materials into a square or rectangular container.

Measure said packing materials.

use geometry skills learned in 10th grade

im getting just under 7 like 6.8 assuming those are outer dimensions using 3/4"

You are a fucking retarded

A triangle is two dimensional; thus no volume.
A prizm is the word you are looking for.

that will get me about 4 1/2 cubes before displacement. Im gonna have to figure out something else

11. ## Re: How the **** do i figure out the volume of a triangle

Area of that triangle = (1/2)(12)(14) + (4)(14)

Multiply it by how many inches you want to extrude it and you'll get its volume in cubic inches.

Divide it by 12*12*12 to get cubic feet.

there is a calculator for that specific box shape on BCAE.

14. ## Re: How the **** do i figure out the volume of a triangle

2.982 cubic feet?

15. ## Re: How the **** do i figure out the volume of a triangle

Just seperate it into two pieces...the rectangle on the right and the triangle on the left....then simply find the area of the rectangle and then just (height x width = y....then y/2 will get you the area of the triangle)...then add that to the rectangle's area and multiply it by your depth of the object for your volume
