Answer:
504 millimeters (or 50.4 cm)
Step-by-step explanation:
- Width of key in student calculator = 14 millimeter (1.4 cm)
- Width of key in demonstration calculator = 2.8 cm
<u><em>Thus, the demonstration calculator's dimensions are </em></u><u><em>twice</em></u><u><em> that of students' (in cm)</em></u>
<u><em /></u>
Also given, student calculator height as 252 millimeters (25.2 cm)
Thus demonstration calculator height will be twice of that = 50.4 cm (or 504 millimeters)
