Answer:
This is a right trapezoidal prism.
To find the total surface area,
First we have to find the area of the 2 trapezoids.
Let us find now.
[tex]Area=2*\frac{1}{2} (a+b)*h[/tex]
[tex]Area=2*\frac{1}{2} (1.4+2.3)*1.9\\[/tex]
[tex]Area=3.7*1.9[/tex]
[tex]Area = 7.03m^{2}[/tex]
Now you have to find the areas of the 3 rectrangles.
Let us find now.
(4.8 × 2.1) + ( 4.8 × 2.3)+ ( 1.9 × 4.8)
10.08 m² + 11.04 m² + 9.12 m²
= 30.24 m²
Now let us find the total surface area of this solid.
7.03 m² + 30.24 m²
= 37.27 m²
