What is the value of the interquartile range of the data below?
25, 30, 35, 40, 45, 50

answers:
a. 4
b. 5
c. 8
d. 13

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 !
