Sample Response: The water molecule has the greater mass because 2.99 is greater than 2.66. After comparing the exponents, which are the same, the coefficients are compared to determine the molecule with the greater mass.
Answer:
392
Step-by-step explanation:
3 rectangular faces
7 x 16 = 112
2 triangular faces
1/2 x 7 x 8 = 28
Total surface area:
112 + 112 + 112 + 28 + 28 = 392
Yes, the last 2 are indeed correct :)
Good job.
