To find the total surface area of the figure, we need to add the areas of all the faces together.
Total Surface Area = 2(13.7cm * 4cm) + 2(13.7cm * 3cm) + 2(4cm * 3cm) + 2(7.5cm * 11.5cm) + 2(7.5cm * 4cm) + 2(11.5cm * 4cm)
Total Surface Area = 2(54.8cm^2) + 2(41.1cm^2) + 2(12cm^2) + 2(86.25cm^2) + 2(30cm^2) + 2(46cm^2)
Total Surface Area = 109.6cm^2 + 82.2cm^2 + 24cm^2 + 172.5cm^2 + 60cm^2 + 92cm^2
Total Surface Area = 540.3 cm^2
Therefore, the total surface area of the figure is 540.3cm^2.
Total Surface Area = 2(13.7cm * 4cm) + 2(13.7cm * 3cm) + 2(4cm * 3cm) + 2(7.5cm * 11.5cm) + 2(7.5cm * 4cm) + 2(11.5cm * 4cm)
Total Surface Area = 2(54.8cm^2) + 2(41.1cm^2) + 2(12cm^2) + 2(86.25cm^2) + 2(30cm^2) + 2(46cm^2)
Total Surface Area = 109.6cm^2 + 82.2cm^2 + 24cm^2 + 172.5cm^2 + 60cm^2 + 92cm^2
Total Surface Area = 540.3 cm^2
Therefore, the total surface area of the figure is 540.3cm^2.
