The surface area of the shape is given as:
[tex]\begin{gathered} A_1=2\times A_{triangle} \\ A_1=2\times\frac{1}{2}\times base\times height \\ A_1=2\times\frac{1}{2}\times0.4\times0.3 \\ A_1=0.12ft^2 \\ \\ A_2=Area\text{ of the rectangular base=0.4}\times2 \\ A_2=0.8ft^2 \\ \\ A_3=Area\text{ of the surface top=}0.5\times2 \\ A_3=1ft^2 \\ \\ A_4=Area\text{ of the rec}\tan gle\text{ on the left side=0.3}\times0.2 \\ A_4=0.06ft^2 \end{gathered}[/tex]Total surface area= 0.12 + 0.8 + 1 + 0.06 = 1.98
Hence, the product of the last two(2) digits is: 9 x 8 = 72 square feet
