The formula for the surface area is 2lw + 2hl +2hw. So, 2(9*12)+2(9*12) +2(9*9)=?
It is 2*(Length*Breadth + Breadth*Height + Height*Length).
To figure out the surface area of a reactangular prism you have to multiply length x width and then multiply that by how many faces it has, to figure out volume you multiply the length x width x height of the prism and than you will find your answer!!!!!
A rectangular prism with a length of 11m, width of 8m and height of 3m has a volume of 264m3
volume=length x width x height so to figure out the answer you need to know the length,width, and height.
The formula for the surface area of a rectangular solid is = 2lw + 2lh + 2wh 2(length x width)+2(length x height)+2(width x height)
Length x Height x 2 Length x Height x 4

the Surface area of a Rectangular prism is (2 x Length x Breadth) + (2 x Length x Height) + (2 x Breadth x Height) By austin from Covenant christian school
a solid figure
The area does not provide sufficient information to determine the length, width and height.
