Question

what is the height of this solid figure? 2in 6in² 9in 2in²

Explanation:

Step1: Analyze the units

Height is a one - dimensional measurement. Units for height should be in inches (in), not square inches ($in^{2}$). So we can eliminate options with $in^{2}$ (i.e., $6in^{2}$ and $2in^{2}$).

Step2: Identify the height from the figure

In a rectangular prism (the solid figure shown), the height is one of the side lengths. Looking at the figure, one of the side lengths is labeled as $2$ in. The value $9$ in is not a side length of the given rectangular prism.

Answer:

2 in
