What is the surface area of the rectangular prism below?
a. 423 units squared
b. 630 units squared
c. 1260 units squared
d. 846 units squared

D. 846 units squared

Step-by-step explanation:

12x9=108

108x2=216

15x9=135

135x2=270

12x15=180

180x2=360

360+270+216=846 units squared

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
