Nets & Views
Fold nets into solids and picture top, front and side views
What your child practises
Matching flat nets to prisms and cylinders, working out what the parts of a net measure, and picturing an object from above, the front and the side.
Alberta Curriculum learning outcome: SS2, SS5 · nets of right prisms and cylinders, and top, front and side views of objects built from rectangular prisms
Sample questions
A taste of this unit. In the app, questions change every time and get easier or harder to match your child.
Question 1
In a net of a cylinder, the length of the rectangle matches the…
- circumference of the circle
- diameter of the circle
- area of the circle
- radius of the circle
Show answer
circumference of the circle
Hint: The rectangle wraps once around the circle's edge.
Question 2
In a net of a cylinder, the width of the rectangle matches the…
- area of the circle
- circumference of the circle
- height of the cylinder
- radius of the circle
Show answer
height of the cylinder
Hint: The rectangle's other side runs from the bottom to the top of the cylinder.
Question 3
Three cubes sit in a row, and a fourth cube sits on top of the left end cube. You look at it from the right-hand side. What do you see?
- a column of 4 squares
- a column of 2 squares
- a row of 3 squares
- a single square
Show answer
a column of 2 squares
Hint: From the end, the rows line up behind each other. The tallest stack is 2 cubes high.
Question 4
A can has a diameter of 11 cm. In its net, one side of the rectangle wraps around the circle. How long is that side? Use π ≈ 3.14 and round to 1 decimal place.
answer boxcm
Show answer
34.5 cm
Hint: Circumference = π × diameter ≈ 3.14 × 11 = 34.54, which is 34.5 cm to one decimal place.
Question 5
A square pyramid's net has how many triangles?
- 5
- 4
- 2
- 1
Show answer
4
Hint: One triangle rises from each side of the square base.
Question 6
