A factory bottles 511 bottles of juice in 7 minutes. Find the factory's unit rate of bottles per minute. A. 511 bottles/7 minutes
B. 73 minutes/1 bottle
C. 73 bottles/1 minute
D. 73:1

511 divided by 7 is the unit rate. So a is how you get it but d is the answer

Volume is length times width times height so
20 times 8 times 30 which is 4,800
surface area is ph (p is perimeter of base), h is height.
so perimeter would be length+length+width+width so 20+20+8+8 which is 56. so multiply 56 times 30 which is 1680. hope this !
