The correct answer is A. 73 books
Explanation:
The first step to find the answer is to know the total volume/space in the bookcase. This can be calculated by using the formula v (volume) = h (height) x l (length) x w (width) or multiplying the three sides given because this is the formula for a cuboid and most bookcases have this shape.
v (volume) h x l x w
v = 36 in x 24 in x 12 in
v = 10368 in
According to this, the total volume of the shelf is 10368 in. The next step is to calculate the volume of 1 book. This can be found using the same process and formula.
1.5 in x 11 in x 8.5 in = 140.25 in
Finally, to know how many books can fit in the bookshelf divide the total volume of the bookshelf into the volume of one book.
10368 ÷ 140.25 = 73.9
Thus, the total books that can be fit in the bookshelf is 73
