To determine the height of the actual pyramid from the given height of the pyramid in the drawing (3 1/2 inches), we need to know the scale used in the drawing. For example, if the scale is 1 inch in the drawing represents 10 inches in reality, we would calculate the actual height by multiplying the height in the drawing by the scale factor.
For instance, with a scale of 1 inch = 10 inches:
-
Convert 3 1/2 inches to an improper fraction: \[ 3 \frac{1}{2} = \frac{7}{2} \text{ inches} \]
-
Multiply by the scale factor (if the scale is 10): \[ \text{Actual height} = \frac{7}{2} \times 10 = 35 \text{ inches} \]
If you provide the scale used in your drawing, I can help you calculate the actual height specifically!
