Incandescent Light Bulb

The light bulb below was created mainly using elementary functions. The curves in the 2D view are functions except for the three vertical line segments. All the components of the light bulb (except the filament) were created in the 2D view and then rotated about the x-axis in the 3D view. The filament was created in the 3D view using a helix.

Inspired by this l ight bulb.

Forming Rectangles with Squares

A unit square is a square with a side length of 1 unit. The rectangle below was formed using 6 unit squares. Its dimensions are 1 unit × 6 units or simply 1 × 6.

TASK

Using the Square tool, form as many rectangles as you can using exactly 6 unit squares.

Question 1

What are the dimensions of the rectangles that you have formed?

Question 2

We know that a 1 × 6 and a 6 × 1 rectangle are just the same rectangle (Why?), so we can count them as one rectangle. Now that we know this, how many rectangles can we form if we use exactly 6 unit squares?

two four one three

Question 3

How many rectangles can we form if we only use exactly 5 squares?

two three many one
