Find the volume of each shape below. Assume that all corners in part (b) are right angles.

  1. Cone
    A cone with a radius, 3, and a height, 10.

    What is the formula for the volume of a cone?

  2. A prism where the base looks like a capital letter, I, and the height is 10. The total height of the letter, I, is 18 while the space between the bottom and top base is12. the base length at the top and bottom is, 21. The width of the center of the letter, I, is 9. The letter is vertically and horizontally symmetric.

    Find the volume of an by by rectangular prism, then subtract the missing parts.
