Unit 4 Prep

Choose the formulas for the surface area of a rectangular prism:

• $S.A.\ =\ 2\left(l\times w\right)\ +2\left(w\ \times h\right)\ +2\left(l\times h\right)$
  

• $S.A.\ =\ b\times h\div2$
  

• $S.A.\ =\ l\times w$

• $S.A.\ =\ 2\left[\left(l\times w\right)+\left(w\times h\right)+\left(h\times l\right)\right]$

• You use the formula that we learned

• You decompose the figure into the shapes it is made of, find their areas and then add

• You google it

• Ask your teacher
