Question

The giant sequoia is the tallest tree in the world, and it can grow to be 80 m

(8,000 cm) in height. If a model used a ratio of 1:800, how tall would the
model of the sequoia tree be?
A. 10 cm
OB. 800 cm
C. 80 cm
D. 0.01 cm

Answer 1

A. 10 cm

Step-by-step explanation:

You want to know the height of a 1:800 model of an 80 m (8000 cm) giant sequoia tree.

Scale factor

The scale factor of a model or drawing or map is the ratio of a dimension of the model to the corresponding real world dimension. That is, the model dimension is found by multiplying the real world dimension by the scale factor.

model height = 1/800 × tree height

model height = 1/800 × 8000 cm = 10 cm

The model of the sequoia tree would be 10 cm tall.
