**Heat equation**

Given the 3-D rectangular solid with sides of length a, b and c in the x, y and z directions, respectively. Find the function T(x,y,z,t) when

Laplace(T)=1/K(dT/dt) subject to the following conditions:

1) Initial conditions: T(x,y,z,0)=0

2) Boundary conditions

a. dT/dx + h(1)T = 0 for x=0

b. T = 0 for x=a

c. dT/dy = 0 for y=0

d. dT/dy = 0 for y=b

e. dT/dz = 0 for z=0

f. dT/dz + h(2)T = 0 for z=c

Anyone plese suggest me, I don't understand. Thank you.
