this rectangular prism is made of unit cubes. what is the volume of the rectangular prism? cubic units
Answer
Explanation:
Step1: Count length, width and height
Count the number of unit - cubes along length, width and height. Assume length $l = 6$, width $w=4$, height $h = 3$.
Step2: Use volume formula
The volume formula of a rectangular prism is $V=l\times w\times h$. $V = 6\times4\times3$ $V=72$
Answer:
72
