Question

What is the surface area of the larger prism? 6 m Demo 3 m 3 m 1 m O m 90 m 2 2 O 60 m O 108 m 2 O 30 m 2

Answer 1

Given data:

The given figure of the prisms.

The surface area of larger prism is,

$\begin{gathered} SA=2((3\text{ m)(3 m)+}(3\text{ m)(6 m)+(6 m)(3 m))} \\ =2(9+18+18)m^2 \\ =90m^2 \end{gathered}$

Thus, the surface area of the larger prism is 90 sq-meter, so first option is correct.
