1. The figure above shows a plane intersecting a cube through four of its vertices. An edge length of the cube is 6 inches. a. Describe the shape formed by the cross section. b. What is the perimeter of the cross section? (Hint: the diagonal cuts the square into two right triangles. Use what you know about right triangles to determine the length of the cross section) C. What is the area of the cross section?

5. Find the height and area of the trapezoid.

You have a 125.0 cm³ of clay. 4. Find the height of a 7.500 cm diameter cone you could make with all the clay. 5. Find the surface area of a 9.000 cm tall cylinder you could make with all the clay. 6. Find the radius of the hemisphere you could make with all the clay.

The radius of the base of a cone is 6 inches. The slant height of the cone is 10 inches. Which is closest to the surface area of the cone? (Hint: Did they give the radius or diameter?)*   A. 60 inches squared   B. 122 inches squared   C. 302 inches squared   D. 829 inches squared
