Question

a teacher is placing textbooks that are 2.5cm thick on a bookshelf.the teacher wants to place 60 textbooks on the shelf . the bookshelf is 160cm long . dose the teacher have enough space on the bookshelf for the textbooks

Answer 1

Explanation:

To determine whether the teacher has enough space on the bookshelf for the 60 textbooks, we need to calculate the total space that the textbooks will occupy.

The thickness of each textbook is 2.5cm, so the total thickness of 60 textbooks will be:

60 textbooks * 2.5cm/textbook = 150cm

Therefore, the total space occupied by the textbooks will be 150cm.

The bookshelf is 160cm long, so we need to check whether the length of the bookshelf is greater than or equal to the total space occupied by the textbooks.

160cm >= 150cm

Since the length of the bookshelf is greater than the space occupied by the textbooks, the teacher has enough space on the bookshelf for the 60 textbooks.
