For this case we have that by definition, the volume of a parallelepiped is given by:
Where:
l: It's the long
w: It is the width
h: It's the height
From the figure we have the following data:
We must find the value of the length of the parallelepiped:
Answer:
Answer: b.14
Step-by-step explanation:
We have two shelves, the top shelf and the bottom shelf
.
Now, firstly we are told the top shelf has 10 more than 1/3 the number of books on the bottom shelf. This can be expressed as:
(1)
Then, we are told there are 12 books on the bottom shelf:
(2)
Substituting (2) in (1):
(3)
(4)
(5) This is the number of books on the top shelf
Hence, the correct option is b.
