Question

janet builds a rectangular prism with unit cubes. janets rectangular prism has unit cubes in each layer. drag a number into each box to complete the statement.

Explanation:

Step1: Count columns and rows

By observing the rectangular - prism, assume the base layer. If we count the number of unit - cubes in the base layer, we can see that there are 2 columns and 3 rows of unit - cubes in each layer.
The number of unit - cubes in each layer is found by multiplying the number of columns by the number of rows. So, the number of unit - cubes in each layer is $2\times3 = 6$.

Step2: Count layers

By observing the height of the rectangular prism, we can see that there are 7 layers of unit - cubes.

Answer:

Janet's rectangular prism has 6 unit cubes in each layer and 7 layers.
