São Luís is surrounded by several beaches with warm waters throughout the year. This capital of Maranhão, a World Heritage Site since 1997, has always received many visitors for its centuries-old cobblestone streets, colonial tiled mansions, and grand literary settings. Consider that a cobblestone in the city streets is made of aluminum, which has a linear expansion coefficient, α = 24x10⁻⁵ °C⁻¹, and that at 40 °C, it has edges equal to 20.0 cm, 10.0 cm, and 6.0 cm. What will be the volume, in cm³, of the cobblestone at 0.0 °C? a) 1165.6 b) -34.4 c) 1200 d) 1188.5 e) -11.5 🔔 Did you like the solution?
