Question

If the height of the knife is 4 inches, then which of the following is the estimated height of the vase?

• A. 15 inches
• B. 5 inches
• C. 4 inches
• D. 9 inches

Answer 1

The correct option is D 9 inches

$\text{Say:}$
The height of the knife = 4 inches.

$\text{Steps:}$
$\bullet$ The height of the vase is nearly double the length of the knife.

$\bullet$ So, the height of the vase is around 4 + 4 = 8 inches.

$\bullet$ By observing the options, we can see that 9 inches is the closest to 8 inches

$\bullet$ Hence, option C is the answer.
