Volume: measuring with unit cubes | Measurement | Pre-Algebra | Khan Academy

Volume is usually measured in cubic feet (or inches, or centimeters, etc). Let's practice counting cubic feet in order to find the volume.

Pre-Algebra on Khan Academy: No way, this isn't your run of the mill arithmetic. This is Pre-algebra. You're about to play with the professionals. Think of pre-algebra as a runway. You're the airplane and algebra is your sunny vacation destination. Without the runway you're not going anywhere. Seriously, the foundation for all higher mathematics is laid with many of the concepts that we will introduce to you here: negative numbers, absolute value, factors, multiples, decimals, and fractions to name a few. So buckle up and move your seat into the upright position. We're about to take off!

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

Thank you for making these videos
they are incredibly helpful :D

...the expression 3x^2 + 3x + 1 exactly describes a way that a cube grows, adding 1 to its edge length each time: E.g., start with the unit cube, then add on this many extra unit cubes for each successively larger cube: 7 -> 19 -> 37 -> 61 -> 91 - > 127 etc. (these are the differences of consecutive cubes.) Geometrically, one can imagine 'pasting' 3 'slabs', each of face area x^2, plus 3 'columns' of x unit cubes, plus a single unit cube to fill the remaining void, completing the slightly larger cube.

I know you can count the squares, but why not do length x width x depth and subtract any duplicates (such as the forth example?)

Can you tell me the answer of this " How many cubic inches are in a cubic foot?"

Pewdepie has 64millions subs, and this channel 4 millions. The day we have more then 64mm subs on this channel, we will reach the stars "literally"
