Area, Surface Area and Volume Volumes of Prisms and Cylinders ● Volume is the amount of 3-dimensional space that a substance (solid, liquid, or gas) occupies, measured in cubic units. ● When working with pi, leaving your answer in terms of pi is the exact answer. If the problem asks you to round your answer, write the full calculator display before you round to the indicated place value. Volume of a Sphere ● Volume of a Sphere = Perfect Square Roots ● When you multiply a number by itself, you are squaring that number or raising it to the second power. ○ For example 3^2 (3 x 3= 9). ● The square root of a number is one of its two equal factors. ○ Every positive number has both a positive and negative square root. ○ A radical sign is used to indicate the principal square root. ○ A negative sign in front of the radical means to find the negative square root. ○ If there is a plus/minus sign in front of the radical, you need to find both square roots.
