Answer 1

Answer:

Shawn's phone is 36 cubic centimeters larger than Ella's.

Step-by-step explanation:

12 by 6 (12*6) = 72 centimeters * 3/4 of a centimeter tall = 54 cubic centimeters in total for Ella, 15 by 8 (15*8) = 120 centimeters * 3/4 of a centimeter tall = 90 cubic centimeters in total for Shawn. 90 - 54 = 36 cubic centimeters larger.
