A teacher is cutting pieces of tape for the marshmallow challenge.The roll of tape is 16.8 meters long and each piece measures 1
Zanzabum

Given:

Total length of tape in roll = 16.8 meters

Length of each piece = 1.125 meters

Number of pieces = 8

To find:

The remaining tape.

Solution:

We have,

Length of 1 piece = 1.125 meters

Length of 8 piece = 8 × 1.125 meters

                              = 9 meters

Total length of tape in roll = 16.8 meters

Remaining tape = Total length of tape in roll - Length of 8 piece

                           = 16.8 - 9 meters

                           = 7.8 meters

Therefore, the length of remaining tape is 7.8 meters.
