Question

in the rectangular prism, each small cube has edges that are $\frac{1}{2}$ inch long. what is the height of the rectangular prism? 1 inch 1$\frac{1}{2}$ inches 3 inches 3$\frac{1}{2}$ inches

Explanation:

Step1: Count height - cube layers

Count the number of small - cube layers along the height. There are 6 layers.

Step2: Calculate height

Each small - cube edge length is $\frac{1}{2}$ inch. Multiply the number of layers by the edge length of each cube. So, the height $h = 6\times\frac{1}{2}$ inches.
$h=3$ inches

Answer:

3 inches
