What is the best approximation of the volume, in cubic units, of a pyramid of height 4 and a square base of length 6?

Geometry Question

Max is building a spherical model of Earth. He is building his model using 2-inch long pieces of wood to construct the radius. The first time he tries to build the model, he uses 3 of the 2-inch pieces of wood end-to-end to make the radius of the model. a) What is the volume of the model in cubic inches? b) In order to purchase the right amount of paint for the outside of the model, Max needs to know the surface area. What is the surface area of the model in square inches? c) Max decides he wants the model to be larger. If he doubles the length of the radius, how many times larger is the volume?

13) The pyramid shown to the left has a square base of length 18 cm and a 0 ss bsau ar (0, height of 12 cm. Determine the nossaiwbobiotn surface area and volume of the pyramid. In your work, show how you would 1) label the figure and 2) explain the process for computing the surface area and volume to a middle school student.
