Presentation transcript:

A cube has a total surface area of 24 cm2 A cube has a total surface area of 24 cm2. If the total surface area is increased by a factor of 4, what is the change of the length of each side of the cube? The length is 2 times the original length. The length is 4 times the original length. The length is 6 times the original length. The length is 8 times the original length.

If the dimensions of a rectangle with an area of 18 cm2 are tripled, what will be the area of the new rectangle? The area of the new rectangle will be 36 cm2. The area of the new rectangle will be 48 cm2. The area of the new rectangle will be 72 cm2. The area of the new rectangle will be 162 cm2.

The scale factor of two similar rectangles is 2/3 The scale factor of two similar rectangles is 2/3. The perimeter of the larger rectangle is 36 cm. What is the perimeter of the smaller rectangle? The perimeter of the smaller rectangle is 72 cm. The perimeter of the smaller rectangle is 18 cm. The perimeter of the smaller rectangle is 12 cm. The perimeter of the smaller rectangle is 24 cm.

Ricky built 2 boxes shaped like similar rectangular prisms Ricky built 2 boxes shaped like similar rectangular prisms. The dimensions of the smaller box are half the dimensions of the larger box. If the volume of the larger box is 24 cubic cm, what is the volume of the smaller box? The volume of the smaller box is 12 cubic cm. The volume of the smaller box is 6 cubic cm. The volume of the smaller box is 3 cubic cm. The volume of the smaller box is 2 cubic cm.

A rectangular prism has a volume of 16 cubic cm A rectangular prism has a volume of 16 cubic cm. If the length, width, and height are all changed to ½ their original size, how does the volume of the new prism compare to the volume of the original prism? The volume of the new prism is twice the volume of the original prism. The volume of the new prism is ½ the volume of the original prism. The volume of the new prism is ¼ the volume of the original prism. The volume of the new prism is 1/8 the volume of the original prism.

Amy built 2 similar boxes shaped like rectangular prisms Amy built 2 similar boxes shaped like rectangular prisms. The corresponding dimensions of the larger box are triple those of the smaller box. The volume of the larger box is 54 cubic cm. What is the volume of the smaller box? The volume of the smaller box is 2 cubic cm. The volume of the smaller box is 9 cubic cm. The volume of the smaller box is 18 cubic cm. The volume of the smaller box is 27 cubic cm.
