Steps:

1. Use the formula V = wlh (basically, multiply each of the dimensions together to get volume)
2. one cubic cm (cm^3) = 1ml, so you can convert volume to mass simply by multiplying volume times density. 
3. Convert mass to moles using the molar mass of tin
4. Use stoichiometry to obtain the number of moles of HCl
5. Convert moles of HCl to grams
