What are the cubic inches for my Sentry Valueguard 1330 safe #1623580?

Volume (in³): 2160 cubic inches

If you want to measure the cubic inches of a container, measure the length, width, and depth in inches. Then multiply those numbers by each other. For example, if your container is 5 inches long, 3.5 inches wide, and 7 inches deep, your calculation will look this: 5 x 3.5 x 7 = 122.5 cubic inches.

What are dimensions for Maytag dishwasher Model # DWU7400AAX?

google maytag dwu7400aax dimensions for your answer less than 3 seconds.


This is just a standard size dishwasher model. Dishwashers in general are going to be standard size unless you get a portable dishwasher or a 30 inch wide dishwasher. There are very few of these models. Your size dishwasher is just 24" wide 24" deep and 34 1/2 inches tall but the height can be adjusted somewhat

How to calculate cubic feet ?

Calculating the cubic feet of a space requires multiplying the area of the bottom times the average height. You get the bottom area by multiplying the length times the width. Remember, to get cubic feet, you need all your measurements in feet to start with.

Here is your formula:

VOLUME (in cubic feet) = Length (in feet) X Width (in feet) X Height (in feet)

If it's a rectangular room you're working with, it is all straightforward. If there are irregular walls, it may be necessary to divide up the room into rectangular sections and then add together their individual volumes. If the ceiling is sloped, you need to use the height that has the same ceiling area above it as below it. Good luck! Truly.

How many jelly beans are in a jar thats 23 inches around and 17 inches high?

V = (pi)(r square)(h) V= Volume (the amount we need to calculate)
pi = 3.14...
r = radius of cylinder (remember this is half that of the circumference)
h = height of cylinder

To make it easier for you below are the figures for the Cylinder.
Radius= 11.5 inches
Height = 17 inches.
Now use the formula above to calculate it.

For the Jelly Bean its,
Radius = 0.25 inches
Height = 0.5
Use the same formula above for jelly bean as well.


Once you have both figures, divide Volume of Jar by Volume of Jelly e.g. VolumeofJar/VolumeofJelly

AND VOILA, you have the amount of jelly beans in a jar (Round the figure out)

Cheers!

I have 8 alpine dvc type r 12s, should i port them or go with a sealed box.

depends what kind of car they are going in and what kind of sound you are going for.
generally speaking ported boxes are louder, if you choose this i would recommend filling box with poly-fill.
non-ported boxes get deeper bass and hit much harder. no matter what set up you choose a good quality box that does not flex is EXTREMLY IMPORTANT. you will want the wood to be at least 3/4" thick and the correct cubic feet.
