  1. Area and volume | Lesson (article) | Khan Academy

    What are area and volume problems? Area and volume problems focus on using the relevant formulas for various two- and three-dimensional shapes. We'll be expected to calculate the length, area, …

  2. Volume and surface area | Geometry (all content) | Math | Khan Academy

    Volume and surface area help us measure the size of 3D objects. We’ll start with the volume and surface area of rectangular prisms. From there, we’ll tackle trickier objects, such as cones and spheres.

  3. Volume intro: how we measure volume | Math (video) | Khan Academy

    Volume focuses on the actual amount of space occupied, while capacity refers to the maximum space available in a container. Both terms are related to measuring the extent of space, but they serve …

  4. Volume of a sphere (video) | Area and volume | Khan Academy

    As you may have seen the derivation of volume of a sphere relies on the area of a circle which would have to be derived in a similar fashion but this derivation relies on the circumference of a circle that …

  5. Perimeter, area, and volume | Lesson (article) | Khan Academy

    Do we need to memorize all area and Volume formulas or do we get a chart in the test?

  6. Area and perimeter | Geometry (all content) - Khan Academy

    Area and perimeter help us measure the size of 2D shapes. We’ll start with the area and perimeter of rectangles. From there, we’ll tackle trickier shapes, such as triangles and circles.

  7. Measuring area and volume (practice) | Khan Academy
