For this you are trying to find the volume which is equal to: [latex]V = L*W*H[/latex] So its probably easier if we make then improper fractions so for number three: [latex]V=( \frac{13}{2})( \frac{8}{2})( \frac{28}{3})=\frac{728}{3}in^{3}=242 \frac{2}{3}in^{3} [/latex] If it is SA, then [latex]SA = 2(LW+LH+WH) = [/latex]  [latex]2( \frac{28}{3}*4+ \frac{28}{3}* \frac{13}{2}+ \frac{13}{2}*4)[/latex] [latex]=2(124)=248in^{2}[/latex] For number 6: [latex]V=(8)( \frac{23}{4})( \frac{5}{2})=115yd^{3} [/latex] or [latex]SA = 2(LW+LH+WH) = [/latex] [latex]2(8* \frac{5}{2}+8* \frac{23}{4}+ \frac{23}{4}*\frac{5}{2})= [/latex] [latex]2(80.375) = 160.75in^{2}[/latex]
