Answer:
The height of the glass in the actual is 10 cm
Explanation:
we know that
The scale of the drawing is
![(2)/(2.5)(units)/(cm)](https://img.qammunity.org/2020/formulas/mathematics/high-school/5260s32eaqq01xe4bi5qxi339oxchi3bho.png)
That means ------> 2 units in the drawing represent 2.5 cm in the actual
Find out the height of the glass in the actual
using proportion
Let
x -----> the height of the glass in the actual
![(2)/(2.5)(units)/(cm)=(8)/(x)(units)/(cm)\\ \\ x=2.5*8/2\\ \\ x=10\ cm](https://img.qammunity.org/2020/formulas/mathematics/high-school/yc9nawbm3cfysb1day2noseew884heeiru.png)
therefore
The height of the glass in the actual is 10 cm
