Enter your answer as a mixed number in simplest form

Answer 1

first off, let's change all the mixed fractions to improper fractions.

Check the picture below.

`\stackrel{\textit{\Large Areas}}{\stackrel{\textit{left and right}}{2\left( (4)/(3)\cdot (5)/(2) \right)}~~ + ~~\stackrel{\textit{front and back}}{2\left( 3\cdot (4)/(3) \right)}~~ + ~~\stackrel{\textit{top and bottom}}{2\left( 3\cdot (5)/(2) \right)}} \\\\\\ \cfrac{20}{3}+8+15\implies \cfrac{89}{3}\implies 29(2)/(3)`
