Application: Crafts
Apply proportional reasoning and linear equations to calculate material quantities and dimensions in crafts projects. Build Grade 9 real-world algebra skills.
Key Concepts
Property Real world formulas, like a cube's surface area ($S = 6s^2$), can be solved using square roots. Explanation Math helps build real things! To find a cube's side from its surface area, use the formula. A length can't be negative, so we only need the positive root in these cases. Examples Cube surface area is 294 in². $294 = 6s^2 \implies 49 = s^2 \implies s = 7$ inches. Square area is 144 m². $A = s^2 \implies 144 = s^2 \implies s = 12$ meters.
