Question

8 fill in the blanks with what would most likely represent each of the following items. a. the area of asia: b. the volume of a single red blood cell: drag & drop the answer 4.46 × 10⁷ square kilometers 1.36 × 10⁻⁶ cubic micrometers 4.46 × 10⁻⁷ square kilometers 1.36 × 10⁶ cubic micrometers note: use ctrl+d to drag the option via keyboard

Explanation:

Step1: Analyze the area of Asia

Asia is a large continent, so its area should be a large positive number in square kilometers. Among the options, \( 4.46 \times 10^{7} \) square kilometers is a reasonable value for a continent’s area (the other square - kilometer option \( 4.46 \times 10^{-7} \) is too small).

Step2: Analyze the volume of a red blood cell

A red blood cell is extremely small. The volume should be a very small positive number (since it is a volume, we consider the cubic micrometer options). \( 1.36 \times 10^{-6} \) cubic micrometers is a very small value suitable for a single red blood cell, while \( 1.36 \times 10^{6} \) cubic micrometers is too large for a single red blood cell.

Answer:

A. \( 4.46 \times 10^{7} \) square kilometers
B. \( 1.36 \times 10^{-6} \) cubic micrometers
