How do you find the perimeter and surface area of a rectangular solid?

Well it depends what your asking, if your just looking for the perimiter it would be length times 2 plus height times 2. Now if your looking for lateral surface area the formula would be length times height times 2 plus length times height times 2,

heres a better look at the formula.

perimiter (P) = L+L+W+W

lateral surface area (LSA) = 2xLxH +2xWxH

Now if your looking for total surface area (The total surface area of a rectangular solid includes the lateral suface area plus the area of the top and bottom) The formula would be.

Total surface area (TSA)= 2xLxH + 2xWxH + 2xLxW

W = Width

L = Length

h = Height

Well I hope that helps
