The temperature of an isotropic cubical solid of length `L`, density `d` and coefficient of expansion `alpha` is raised by `10^(@)C`. To a good approximation, at final temperture

Options

A. length is `L(1+10alpha)`
B. surface area of any face of the cube is `L^(2)(1+20alpha)`
C. density is `d(1+30alpha)`
D. density is `d//(1+30alpha)`

Explanation

Use `L=L_(0)(I+alpha t).A=A_(0)(1+2alpha t)` and `d=(d_(0))/(1+3 alpha t)`
