Worksheet: Similarity of Solids
In this worksheet, we will practice identifying similar solids and using the similarity to find their dimensions, areas, and volumes.
The figure shows two cubes. If the area of the smaller one is 143, and the sides are in the ratio , what is the surface area of the larger cube?
A pair of regular triangular pyramids are similar. Pyramid A has a base side of 17 inches and a slant height of 20 inches, whereas pyramid B has a base side of inches and a slant height of 42 inches. Determine the value of .
A pair of rectangular prisms are similar. Prism is 104 by 32 by 24 inches, while prism is 26 by 8 by inches. Find.
A pair of cylinders are similar. Cylinder A has a base radius of 29 inches and a length of 6 inches, and cylinder B has a base radius of inches and a length of 18 inches. Determine the value of .
The surface areas of two similar solids are 64 square yards and 361 square yards. Find the ratio of their linear measures.
The given pair of rectangular prisms are similar. If the surface area of the smaller rectangular prism is 310 yd2, determine the surface area of the larger one.
A cone has a volume of 11,756 cubic centimeters. Suppose that its dimensions were reduced as the figure shows, find the volume of the resulting cone.
The Newton High School Cheerleaders are making megaphones out of cardboard for a big game. The megaphone is a large cone, as pictured, with a small cone removed in order to shout the cheers through and amplify one’s voice.
Given that the cones are right cones, identify the height of the smaller cone.
Find, to two decimal places, the surface area of the cardboard which makes the small cone.
What is the scale factor of two similar cylinders whose volumes are 1,331 and 1,728 cubic meters?
