Question

what is the volume of this rectangular prism? a 12 cubic units b 13 cubic units c 30 cubic units d 60 cubic units how many cubes are in each layer?

Explanation:

Step1: Count length, width and height

Count the number of unit - cubes along length, width and height. Assume length $l = 5$, width $w= 3$, height $h = 4$.

Step2: Apply volume formula

The volume formula for a rectangular prism is $V=l\times w\times h$. So $V = 5\times3\times4$.

Step3: Calculate the volume

$V=60$ cubic units.

Answer:

D. 60 cubic units
