To find the scale factor, divide the corresponding dimensions on the scale drawing by the actual dimensions. For the length, 40 ft is equal to 480 in, so the scale factor is 16 in / 480 in = 1/30. For the width, 28 ft 9 in is equal to 345 in, so the scale factor is 11.5 in / 345 in = 1/30. MarΓ­a used a scale factor of 1/30 in her drawing.

What is the difference between scale drawing and ordinary drawing?

A 2-dimensional drawing would be comprised of flat shapes: squares, rectangles, triangles, circles, etc. A 3-dimensional drawing would be made of shapes that imply depth: cubes, pyramids, cones, spheres, etc. A scaled drawing is referenced to an "original" drawing or object and is proportionately the same as the original. Scaled drawings allow one to draw the original in a larger or smaller size (scale) without changing how the individual parts of the original relate to each other.

Why is it important to record the magnification used when drawing cells?

Recording the magnification used when drawing cells is important because it provides critical information on the scale and detail of the drawing. This helps ensure accuracy and allows others to understand the size and features of the cells depicted. Additionally, it enables researchers to replicate and compare the observations made under the same magnification.
