To determine the volume of the prism?
12. Distribute 1-cm cubes, a ruler, and a
rectangular prism with 4 rows, 3 columns,
and 10 layers. Ask them to work together
and find the volume using the rows,
columns, and layers. Aside from counting
the number of cubes and multiplying the
number of rows by the number of columns
and by the number of layers, ask them to
think of other ways to find the volume.
13. Solutions: By measuring the length, width,
and height using a ruler.
By relating the number of
rows, columns, and layers with width,
height, and length of the container.
By multiplying the length l by
the width (w) and by the height (h).
V = l x w x h
= 10 cm x 4 cm x 3 cm
= 120 cm3
14. How do you find the volume?
The number of
cubes is the volume
of the rectangular
prism.)
15. How did you find the volume
aside from counting the
cubes?
By multiplying the
number of rows by the
number of columns and
by the number of layers.
16. What did you do with the
measurement of the length,
width, and height?
We related length with
rows, width with
columns, and height
with layers.
17. What is the formula in finding
the volume of a rectangular
prism?

29. How do you find the volume of a
rectangular prism?
Volume is measured in
cubic units, such as cubic
centimeters (cm3), cubic
meters (m3), and cubic
millimeters (mm3).
30. How do you find the volume of a
rectangular prism?
Use V = l x w x h to find the
volume of a rectangular prism.
Here, l is the length, w is the
width, and h is the height of the
rectangular prism. Use V = s3 to
find the volume of a cube. Here,
s is an edge of a cube.
