Question

A factory builds a new warehouse that is approximately 1.28x10^5 square feet. Later, they add on 1.13x10^3 more square feet for offices. Use scientific notation to write the total size of the new building.

Answer 1

The correct answer is 1.2913 x
`10^(5)` square feet.

Explanation:

A factory builds a new warehouse that is approximately 1.28 x
`10^(5)` square feet = 128,000 square feet.

Later, they add on 1.13 x
`10^(3)` square feet = 1,130 square feet more for offices.

Thus the total size of the new building is given by 128000 + 1130 = 129130 square feet = 1.2913 x
`10^(5)` square feet.

Thus in scientific notation the total area of the factory is 1.2913 x
`10^(5)` square feet.
