A mailing service places a limit of 36 in. on the combined length and girth of (distance around) a package to be sent parcel post. What dimensions of a rectangular box with square cross-section will contain the largest volume that can be mailed? (Hint: There are two different girths.) X

19 in. What is the volume of a triangular pyramid that is 9 inches tall and has a base area of 18 square inches? V = [?] cubic inches Hint: Volume of pyramid = Bh (B = area of the base) Enter

A diagram of a paper tube is shown below. Find the volume of paper making up the tube.

a. Suppose we had a triangular prism that was 14 cm long with atriangular base of 1 cm and a height of 0.8 cm. Whatwould the volume of that prism be, and do youbelieve that it actually is a better estimate? b. Suppose that we had a marker that was twice as thick and twice as tall, but the same length. Approximately how many of the cubes would we need to make a good estimate of its volume? Explain/show how you know this.
