How to calculate the thickness of foil?

I have a physics assignment where I have to find the thickness of a sheet aluminum foil only given the fact that a sheet hast the density of 9.7 x 10^-2 lb/in3The only information I have is the sheet weighs 3.77 grams and it's base 30 cm and It's height is 28.8 cm.You don't have to solve it for me, I was just wondering how I'd go along the lines of solving itThanksAlso, I googled and found the actual density, which is 1.54 x 10^-3, but I need to show work :PSo don't just give me the answer.

Answer:

A basking bulb would probably emit more heat than a ceramic wouldYou can also try an Under Tank Heater that sticks to the bottom of the tank (on the outside).
umm maybe it would help a lil more but i suggest u get a heat bulb.there better
Keep units consistent by converting any given or measured values to SIYour sheet of aluminum is 30cm x 28.8cmIn SI units it is 0.30m x 0.288m (you know how to do this, right?)Change the cumbersome density in lbs/in? to kg/m?, and the mass from 3.77grams to 0.00377kgNext, density is: ρ m / V Solved for V: V m / ρ And volume is: V ?wh-(h is thickness) So then: ?wh m / ρ Solved for thickness, h: h m / ρ?w Hope this helps.
Since you covered most of the tank top with tape do you have enough ventilation for the lizard or whatever is it you have? Just checkingI use towels on top of the tanks in the winter to hold in heat so I'm surprised that your tank isn't holding enough heatNo you do NOT want to wrap the dome in something to draw the heat downward, ceramics can overheat and explode if not given enough ventilation, that is why they suggest the open dome and not a closed oneI don't remember if they make different sizes for the same wattageYour safest bet is to up wattage.
