Question

Round to the appropriate number of significant digits. \[ 6.0 rm{ft} \times 8.493 rm{ft} \]

Answer 1

51 ft²

Step-by-step explanation:

To determine the appropriate number of significant digits in the product, we need to consider the significant digits in each factor.

6.0 ft has two significant digits.

8.493 ft has four significant digits.

When multiplying, the rule is to use the least number of significant digits among the factors. In this case, we have two significant digits in 6.0 ft.

Performing the multiplication:

6.0 ft × 8.493 ft = 50.958 ft²

Since we are limited to two significant digits, we need to round the result.

Rounding 50.958 to two significant digits, we get:

50.958 ft² ≈ 51 ft²
