Now you are ready to create
a net to satisfy prearranged dimensions. You will be making a pyramid
to the specifications that we give you.
Here is what you need to do:
- Make a net for a RIGHT
SQUARE PYRAMID that has a 6 inch square base and is 3 inches tall.
Be sure to write all the dimensions on the net.
*Note: the height of the triangles on
the lateral sides will NOT be 3 inches. The pyramid itself is 3 inches
tall, so those "slant sides" formed by the triangles will
actually have longer altitudes than three inches. You will need to use
the Pythagorean Theorem to find them. Check
out our example if you need help.
- Cut out your net. Glue it
together carefully. This activity is evaluated by measuring your finished
figure. Your pyramid must pass the test of having a 6 inch square base
and be exactly 3 inches high.
- On the front of a piece
of notebook paper, explain in words how to find the surface area for
your pyramid, and show the mathematics. Be
sure you are very clear about how to find the heights of the lateral
triangles using the Pythagorean Theorem.
- On the back of the notebook
paper explain how to find the volume for your pyramid and show the mathematics.
- DON'T use the same
dimensions as our example.
