What volume is shown in this graduated cylinder?
Explanation: On this graduated cylinder there are 5 tick marks from 10 mL to 15 mL, so each tick mark represents 1 mL. The bottom of the meniscus is halfway between the tick marks representing 13 and 14 mL, so the best estimate of the volume is 13.5 mL.
How can you measure volume?
Units of Measure
- Volume = length x width x height.
- You only need to know one side to figure out the volume of a cube.
- The units of measure for volume are cubic units.
- Volume is in three-dimensions.
- You can multiply the sides in any order.
- Which side you call length, width, or height doesn’t matter.
What is the volume of liquids?
Measuring the Volume of a Liquid At its most basic level, volume is simply a measure of space. When measuring the volume of a liquid, sometimes referred to as capacity, the units liters (L) and milliliters (mL) are used. Devices used for this measurement include graduated cylinders, beakers, and Erlenmeyer flasks.
How do you find the volume of Apothem?
The word “apothem” can also refer to the length of that line segment….Volume of Prism.
| Volume of triangular Prism | V = Area of triangular base x height(H) V = ( base x height) / 2 x H |
|---|---|
| Volume of Pentagonal Prism | Volume = area of base x height(H) V = (AP/ 2) x H ( A = apothem ; P = perimeter) |
What is the formula for surface area of a prism?
The general formula for the total surface area of a right prism is T. S. A. =ph+2B where p represents the perimeter of the base, h the height of the prism and B the area of the base.
What are the formulas for surface area?
We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.
Why volume and surface area is important?
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. That is why cells are so small.
