Question

Find the surface area. Please help!! I need it quick

Answer 1

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.

$Area=2*\frac{1}{2} (a+b)*h$

$Area=2*\frac{1}{2} (1.4+2.3)*1.9$

$Area=3.7*1.9$

$Area = 7.03m^{2}$

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
