What should be the height of the doghouse in his scale model? He wants the actual height of the doghouse to be 6 feet. The scale factor he used for this model was 1/24.

Luis made a scale model of the doghouse he is going to build.

What is the length of the housefly in Sydra's drawing in centimeters?.

What is the length of the housefly in Sydra's drawing in millimeters? The actual length of the housefly was 8 millimeters. So she made a scale drawing, using 10 as a scale factor.

Sydra observed a housefly that was too small to draw at its actual size.

What will be the length, in centimeters, of the metal pipe in his drawing? The scale factor for his drawing will be 1/100. Josh wants to make a scale drawing of the pipe.

If the scale factor was 1/72, what would the length be in inches of the model boat?.

What should be the length, in inches, of the model boat? The scale factor she used for the model was 1/36. The actual length of the boat is 24 feet. If the distance from Calvin’s house to his Grandmother’s was halfway between his and Frank’s, what would be the distance on the map in centimeters?.If the distance from Calvin’s house to the corner store is double the distance from his house to Frank’s, what would be the distance on the map in centimeters?.If the distance from Calvin’s house to the park is 40 meters, what would be the distance in centimeters?.What should be the distance, in centimeters, between those two places on his scale drawing? The actual distance between Calvin's house and his best friend Frank's house is 80 meters. The scale factor he used for his map was 1/800. Calvin drew a map of his neighborhood.Keep in mind that several problems may have more than one part. Scale factors can be used to determine both scale and actual sizes or dimensions. It differs because it does not give any specific units.Ī scale factor for a scale drawing might be 1/200, which means that the actual size is 200 times the drawing.

It is a ratio that compares scale dimensions to actual dimension. Unit scales and proportions can be used to calculate actual distances from maps, drawings, or models.Īctual distances can be represented on maps, drawings, or models by using unit scales.Ī scale factor is somewhat like a unit scale. To represent a line 500 feet long, the unit scale would be used to draw a line 2(1/2) inches long.Ī line 4 inches long would represent an actual line of 800 feet. The unit scale on a map may read 1/2 inch=100 feet. Neither value in a unit scale has to equal 1. Ratios can be written as fractions, with a colon or with the word “to.”Ī proportion is created when two ratios are found to be equivalent or equal.Ī unit rate is a comparison of two measurements, one of which has a value of 1.ĥ5 miles per hour, 55 miles/1 hour is a unit rate.Ī unit scale is a ratio that compares the dimensions of an actual object to the dimensions of a scale drawing or model that represents the actual object.
