From 11:00PM PDT on Friday, July 1 until 5:00AM PDT on Saturday, July 2, the Shmoop engineering elves will be making tweaks and improvements to the site. That means Shmoop will be unavailable for use during that time. Thanks for your patience!

Surface Area and Volume

Surface Area and Volume

Surface Area and Volume: Surface Area 51 True or False

1. Which of the following solids is NOT a polyhedron? -> Triangular prism
2. What is the minimum number of orthogonal drawings needed to construct a perspective drawing? -> 1
3. What kinds of solids are the Platonic solids? -> Polyhedrons
4. What is the difference between an orthogonal drawing and a net? -> There is no difference between a net and an orthogonal drawing
5. Euler's formula says that the number of faces plus the number of vertices in a polyhedron equals the number of edges plus 2. Euler's formula does NOT apply to which of the following solids? -> Pyramids
6. On a starry, starry night, you look up in the sky and see an enormous spaceship that looks like a cone. It lands in front of you and you see that it's made of sheet metal. If the height of the cone is 50 feet and its base has a radius of 20 feet, the spaceship is made out of about how much sheet metal? -> 3800 square feet
7. The aliens step out of their spaceship. They look like square pyramids with green, rubbery skin. If the aliens are 4 feet tall and have a square base of 4 square feet, how much rubbery green skin do they have? -> 16 square feet
8. You try to run away, but the aliens generate a blue force field around you in the shape of a cylinder. Now you're frozen in midair. The radius of the cylinder is 3 feet and it's 6.5 feet tall. How much surface area does the force field cover (including the bottom)? -> 179 square feet
9. The aliens tell you that Zargon, their home planet, has a diameter of 10,000 miles and is completely covered in gold foil. (Don't ask us why. They're the aliens, here.) How much surface area does the gold foil cover approximately? -> 78,500,000 square miles
10. Before the aliens release you and return to Zargon, they give you a walkie-talkie in the shape of a rectangular prism so that you can communicate with them in the future. If the walkie-talkie is 3 inches long, 2 inches wide, and 5 inches tall (with an antenna for long-distance communication), what's its surface area? -> 60 square inches
