This diagram shows the net of a triangular prism and its dimensions. What is the total surface area of the triangular prism?
Train A travels 70 meters in 2 seconds. Train B travels 150 meters in 3 seconds. Which train is faster?
How is the relationship between the scale factor and perimeter different from the relationship between the scale factor and area?
