A.

If a solid has 8 vertices and 16 edges, how many faces does it have?

A. 10 faces

Find the volume of the composite solid if the diameter of the cone is 18.6 inches and the diameter of the cylinder is 22.5 inches. Round your answer to the nearest hundredth.

A. 5,456.68 in3

Find the surface area of the composite solid.

A. 502 m2

Find the surface area of the cone. Round your answer to the nearest hundredth.

B

The two right triangular prisms are similar. Find the surface area of the larger prism. Round your answer to the nearest hundredth.

B.

Which net diagram cannot be folded into a triangular pyramid?

B.

If the radius of the Earth is roughly 3,960 miles, how many times larger is the volume of the Earth than the volume of a ping-pong ball? A ping-pong ball has a radius of 0.7441 inches. 1 mile = 5,280 feet.

C

If the side length of a square pyramid is tripled and the slant height is divided by 5, what would be the formula to find the modified surface area?

C

Which of the following represents the isometric view of the object shown in the orthographic diagram above? The yellow side is the front.

C.

A square prism has a base length of 5 m, and a square pyramid of the same height also has a base length of 5 m. Are the volumes the same?

C. No, because only the bases have the same area, not every cross section at every level parallel to the bases.

How does the volume of an oblique cone change if the height is reduced to 2/5 of its original size and the radius is doubled?
