Not a question but need a lot of tips
More than one answer too
As seen in the image above, that is how my Physics road construction model is supposed to be like. Now that I've drawn a draft, I need some tips on how to actually model it.
What materials I need, how to build it, etc.
I'll award more points ​

A47.2 g block of copper whose temperature is 480 k is placed in an insulating box with a 91.8 g block of lead whose temperature is 200 k. (a) what is the equilibrium temperature of the two-block system? (b) what is the change in the internal energy of the two-block system between the initial state and the equilibrium state? (c) what is the change in the entropy of the two-block system? the heat capacities of copper and lead are 386 j/kg·k and 128 j/kg·k, respectively.
