Calculate the length and volume for a 200 cm on a side copper cube at 20°C, if the temperature is increased to 150°C.
Step-by-Step
\text{New length } = 200(1 + 9.4 × 10^{-6} × [150 − 20] × 9/5) \\ \quad \quad \quad = 200(1 + .0022) = 200.44 \ cm \\ \text{New volume } = 200^{3}(1 + 29 × 10^{-6} × [150 − 20] × 9/5) \\ \quad \quad \quad = 200^{3}(1 + .0068) = 8054400 \ cm^{3}
