Question

how many cubic centimeter blocks are in the bottom layer of the prism shown below? 3 4 7 12

Explanation:

Step1: Calculate the area of the bottom layer

The bottom layer of a rectangular prism has an area calculated by multiplying its length and width. Here, the length is \(3\) cm and the width is \(4\) cm.
$$3\times4$$

Step2: Get the number of cubic - centimeter blocks

Since each block is \(1\) cubic centimeter (\(1\times1\times1\)), the number of blocks in the bottom layer is equal to the area of the bottom layer.
$$3\times4 = 12$$

Answer:

12
